Finally, the first Filipino step wedge test video! This is VERY helpful sir!
Thankful that i found this channel, you make things real "Easy" without making it too complicated unlike other channels out there, which also leads us to buying their expensive tutorials. Thank you for sharing your easy hacks. Keep it up and may you be blessed with lot of projects!
i know I am kinda randomly asking but does anyone know a good place to stream newly released tv shows online?
After a week of youtube research, I finally found your channel. Salamat idol.
:)
I'm just starting screen printing and your video tutorials are the best
:)
Very good video. I have done today this experiment with 30 W Havell LED light which I bought from a local store at INR 425.00. Exposing the screen for 2, 4, 6 & 8 minutes gives very good result. I use SONAKOTE & Bichromate sensitizer. 2 pouches of sensitizer (each 3.5 gms.) should me mixed thoroughly with 100 ml water. Take SONAKOTE according to your requirement and mix the diluted sensitizer thoroughly. Leave the imulsion in a coll dark place at about 1 hour to get rid of the bubbles. Coat uniformly on both side of the screen and make the screen dried in a dark chamber. As to the proportion of SONAKOTE & sensitizer it requires some experiment though one teaspoonful of sensitizer is enough for 50 ml. SONAKOTE. Thanks.
I'm glad that you got it!!!!
Thanks for this Video. Very informative. Now atleast i have an idea about photo emulsion and the exposure time.
Thanks for watching my videos....
Thanks again sir easy...your videos are very helpful po para sa amin na may hilig din sa pagscreen print...again sir easy...big thanks & God bless po...
Salamat and God bless you Too....:)
While starting the screen printing for very first time, i find the best platform to learn 😊 Thanks buddy
You're welcome!
sir I followed your method using the emulsion ER and I got 6min din po at 4min for halftone. laking tulong ng video nyo po.thanks a lot
You're welcome and goodluck!
Step by step talaga idol. Thanks for sharing the knowledge. Great help.
Thanks....:)
Thankyou sir for sharing this with us.this is really helpful!! No skipping ads as repay haha!!!
Thanks....:)
I always enjoy and when I “watch and learn” from your info.
Thanks!
Brilliant idea. I was wondering how I was going to determine my exposure times. Now I know! Thank you!
Glad it was helpful!
mrming salamat sir sa mga video tutorial..laking tulong sa aming nag uumpisa p lng.
Thanks for Watching.....
Your video tutorials are the best,thank from Myanmar!
Thank You!
After a long time I am watching your video again. Love them.
Thank you!
Wow thanks a lot i learned all screen printing in your channel
And also I'll try my LED experiment tomorrow
Good luck!
@@EasyVideos salute sir... the best ka talaga. tanong kolang sir, may fb po ba kayo?
Meron po kaya lang walang Content yung Fb ko :) , facebook.com/Simple-Art-Rocks-549108202087332/
wow, this tuts i'd been looking for. This can determine exposure time whatever wattage, distance of light or brand of emulsion you used. Thanks
Thanks for watching!
Thank you Sir. A very nice experiment to determine the right exposure time. You really take great efforts to teach us these simple & basic tutorials. I think that the slightly uncleared numbers from 14 to 24 due to overexposure will give a cracked & rugged kind of print detail. Personally I prefer this cracked print designs more than the fine detailed ones. Again thank you Sir. I have subscribed your channel.
Many thanks
I am planning to start my own screen printing as a hobby your videos are so helpful. Love from nepal!
Best of luck!
For fast and best exposure take of plastic protector from lamp. Because plastic can stop uv light..
Nice video thank you 👍👍🇩🇿🇩🇿
Thanks for sharing
fantastic video very helpful. Thank you
never thought of this 😭❤
:)
Sir tnx po... Based on ur tutorial, i figured out ilang minutes dpt nkaexpose kht na iba ung watts n gmit ko. . God bless po
:)
You have a new fan and follow. Thanks for the great video.
Awesome, thank you!
Your video is great! very easy to follow. I have great result using your method combine with sunlight. I wanted to try LED light, so I went out to buy a similar strength LED light, the one I got is a 27W, 1500 lumens LED flat lens ceiling spotlight. I didn't buy a bulb with a separate light base. After 13 minutes of exposing from 20'' away... nothing happens. I can't see the white mark on the screen when I lift away the film to check... Can you tell me what was wrong?
Maybe you need to Expose it More...Sometimes Different Brand of Photo Emulsions have different Exposing Time.....
I am sure you have solved your problem by now, but make sure the LED has a full spectrum or "daylight". Some bulbs exclude some of the wavelengths and don't have enough UV.
this is SO helpful! thank you
You're so welcome!
Salamat po dito galing Pinoy!
Hi, thank you so much for the video, this is really really helpful. I am confused about the lighting you are using. After the first dry you take it to do another coat with the light on is it right? Does it not expose the screen to that light?
Not really...but it doesn't have to be that dark while you are coating the screen...
Many many thanks Sir.... Many doubts are clear this video. Plz help how to clean screen.
Ok. Thanks
Hehe now we have ideas... 2mins. Is enough
questions re screen prep: how long should it take for the emulsion to dry and the screen to be properly exposed in a 500-watt halogen lamp? and how far should i place the screen from the light source?
The Photo Emulsion Dries within 15 to 30 minutes using Electric Fan, you have to Experiment determine the Right Exposure Time for your 500-watt Halogen lamp and the Distance is 20 to 30 inches from the Screen....:)
u had a brilliant mind sir thank u
Many thanks
Great tutorial! But I would like to know if this an ordinary 30 watts energy saving led light that we use in lighting up our homes or UV light.
Yes, you can use that.
@Easy
thank you for your tutorial sir.
all your t-shirt printing tutorials are very informative.
Do you mind to share the song title towards the end of the video?
thank you.
Thanks....BoogieBounce is the Title of the Song (Track)....
@@EasyVideos thank you sir
You are a genius bro. Thanks.
Thank You.....:)
Thanks a lot
Thank for watching my videos.....
kaya naman pala nasisira yong emulsion ko kasi 30 mins yong exposure ko... huhuhu. gonna try this one. thanks boss
Good luck....:)
Thank u very much ..nice method n idea
Thanks for liking
Thanks...Cool and easy!!! Do you use white led or ultraviolet led?
White LED....
@@EasyVideos gracias amigo!!!
Question i have a 250watts halugen light, will it work to burn my screen print or do i need to buy a Led Light like yours? Thanks
You can use Halogen Lamp, it will work too....
Hey bro first I appreciate all this tutorials you are helping us with...I have been trying to screen print and for my exposure unit I use a 200w led light and been exposing my screens for 4 minutes...I am yet to have a successful print. Some paint passes through the screen and destroys everything...where am I going wrong?
It seems that your Screen stencil easily break during printing, these are some possible reason- 1.) maybe you need to expose you're screen to led light some more, maybe 5 or 6 minutes. 2.) Maybe you need to apply hardener on you're screen stencil and 3.) Maybe its the brand of Photo Emulsion.
Great video. But If using 50 Watt i think should to decrease the time by 2 minute not increase because to more powerful light source..
By the way im using pre- mix emultion the blue color one..using 50 watt LED 18 inch distance and expose for 8 minute.
Ok....you have to experiment to get the Right Exposure Time....
Is Photo hardener compulsory ???
Thank you for all the info. What mesh/fabric do you use for your frames please
I used 100 mesh screens...
This video helps me allot thanks
Glad to hear it!
what is the difference between green and yellow emulsion? does the 2 year old emulsion work properly?
The difference is just the color, maybe it's just the brand. I will not suggest a 2 year old Photo Emulsion, it might be expired already.
Thank you somuch!🙏
You're welcome!
@@EasyVideos sir bakit po sa gilid ng design nag zizigzag need ba ng glass para ipatong tuwing ibuburn mo sa araw?
Hi when you apply the emulsion do the room have to be dark
It doesn't have to be that dark...dim area is ok...
This is awesome! I wonder will it work if I use LED light strips?
I think it will work too...good luck...:)
What type of emulsion are you using?Also when you attach the silk on the screen you dont put much pressure to stretch the silk,,you dont have any issue regarding the dullness of the silk?
It's was well stretched even if I only use my hand attaching the screen and no problem at all during printing :)
sir tanung k lng din po kc po ang gamit k photo emulsion kulay blue need po b gamitan ng sinsitizer at san b dpat ibilad yun s araw b o s ilaw
Ready Mix na po ata yun....di na kailangan ng Sensitizer....
SALAMAT SIR!
Sir Easy, thank po sa mga tutz nyo. Very helpful. Ask ko lang din sana kung naka gamit kana ng Daizo Photo emulsion? Gaano katagal ang exposure time nya? Salamat po sir in advance. Mabuhay kayo!🙂
di pa po ako naka-gamiy ng Diazo Photo Emulsion.....
Easy ganun po ba. Sir Tulco Aquasol ER po alam nyo gaano katagal i expose sunlight? Kung exposure unit po ilan wattz po ang need ng bulbs at gaano katagal i expose? Salamat po sir Easy in advance.
Thanks for this sir! It helped me a lot! Do you have any idea exposure times and techniques for cmyk?
Using the same LED i used in this Video 5 minutes will be ok...
supposing i don't have a blower or electric fan , how long should one let the photo emulsion to dry bfo applying another coat on the screen?
If you Notice that the the Photo Emulsion is Dry you can apply second coating Right-away...it's easy to identify if the Photo emulsion is already dry....
@@EasyVideos thank you sir
Best video. Salamat po
Salamat! :)
Thank you sir you are genius. Sir i have 16 wats led light so what tine i should take. Because my emulsion always hard
You have to experiment to determine the right Exposure time......
Hello! I'm brazilian. Why your emulsion is yellow, and what is the orange liquid that you pass after the development?
There are different colors of photo emulsion when mixed with sensitizer, the orange liquid I applied on screen stencil is hardener, it will make the screen stencil durable....although there photo emulsion that don't need a hardener...
Helpfull soo much thankyou thankyou sir.
Thanks for Watching......
In my country use oil and paper too for making film screen. Are you use black paper you print it to cover the screen expose
Yes I use Black Board to Cover the Numbers so that Light Cannot Penetrate the Black Board....
Thank you sir!
You are welcome!
Kahit po ba iba ung gamit na emolusion ganun padin ung distance sa ilaw..? Kase gamit ko pong emolusion ung sa tulco ung ready to use na.. Hindi na nilalagyan ng senisitacer.. Madalas po kase hindi maayos ang pag ka expose ko ee.. Help naman po tsaka maraming salamat sa mga videos nyo..
Cguro gawen mo din ung ginawa nya.. Para makita mo wat time ang best
Sir! Napaka-useful ng tutorial na ito. Salamat po. May itatanong lang din po sana. Ano po kaya possible reason kung bakit lagpas-lagpas yung pintura nung na-print na po sa shirt?
Maaari po na hindi pa ganoon ka pulido ng pagkakagawa ng screen stencil, pwede rin po na hindi kayo gumamit ng Soft/shirt pad, pwede rin namang sobrang diin ng Hagod sa Squeege, Pwede rin na hindi ganoon kalapat ang screen Stencil sa t-shirt habang nagtatatak....pag nasanay na po kayo o lagi nyo nang ginagawa madali nyo na ring malalaman kung saan nagkakaproblema....
what if we have a logo design or a single design like face..? in general how many minutes to expose a single design?
Base on that experiment 6 minutes....
Which color is on the school dress T-shirt and by what name is it known?
What will be best time for 500watt led light
You really have to experiment to know the Right time
Good experiment
Thanks....
are u taking a printout using normal paper oly.
Yes normal bond paper...
What stand are you using? Thank you for this video.
...
Hello Sir Easy, kindly explain what you mean by halftone , regular designs and fine detail
fine Detail....czcams.com/video/T1oZS7ykP-0/video.html
Sir can i use butter paper in epson inkjet printer
If you can print on Butter Paper you can also use it....
All Fund's one size... exposing timeing different different....
is it not a good idea to just immerse the screen in a pot of water as the emulsion will soften for a while and then we can wash it with a soft scrub ?
Great videos again.
Thanks
Never Tried it before but I think you can also do it that way....
Am using blue emulsion with red and blue paint but the printing is not coming out what colour of paint should I use?
The Design on the screen stencil did not wash-off during washing that's why there's no opening for the paint to pass through....
@@EasyVideos do u have any video on universal classic heat transfer paper using iron
Witch positive paper are you using
Ordinary bond paper, A4, short or long size paper...
Had to like to even it out to 700. I just started getting into screen prints. Have a hard time getting the cure right on the emulsion itself. Seems to want to wash off screen. Is there a trick to getting it to dry harder?
Sometimes you just have to do it more (Photo Emulsion Developing) to figure things out....thanks for the visit...
Hello I have a question every time I expose 2,4,6,8,10 minutes all ways wash off everything. Why ? My light source it’s two lamps. 25 watts each so it’s 50 w. I ready change two different emolutions
Are you using LED? maybe you need to expose it more than 10 minutes, since we're using different LIGHT SOURCE, Exposure Time also varies....
Easy I’m using uv light it’s like blue
Do you put second time emulsion on same side of the screen? Thanks
Yes...
Hello sir..tanong ko lang, pag water based ba ang ginamit na pintura, gaano katagal patutuyuin tsaka anong klaseng pagtutuyo??kelangan ba nakabilad sa araw or kelangan lang naka sampay at nahahanginan lang..magtatry kasi ako mag screen print po...salamat....
Ok lang pong Ibilad sa Araw, gamitan ng Electric Fan or Blower at pwede rin Pabayaan lang naka-Sampay...15-60 minutes tuyo na po iyon...mas mabilis pa pag maiinit ang kapaligiran o Panahon...
Which photo emulsion do u use...
I usually used TULCO (local) photo Emulsion.
How much the emulution take to dry
And exposing time of under sun light
After coating the Screen with Photo Emulsion let it dry in a DIM area, you can use electric Fan to dry it....then if you will Expose it to SUNLIGHT be sure not Over-Exposed it...10 SECONDS is enough....
स्कूल ड्रेस टी-शर्ट पर कौन सा रंग है और इसका नाम किस नाम से जाना जाता है?
How do u determine 4 to 6mns for fine détails and halftone. And 6 to 10 mns for regular ? Please
I based it on the Experiment I conducted on the featured Video...you can determine the Right Exposure Time during WASHING of the EXPOSED Screen Stencil....MINUTES were REPRESENTED by NUMBERS, when I WASHED the SCREEN 4-6 Washout Easily and therefore I Concluded that 4-6 minutes is best to use in EXPOSING Fine or HALFTONE IMAGES.....I conducted the Experiment because this is the FIRST Time that I will use this kind of LED Light, and I want to Determine the Right Exposure Time for this kind of LED....

are u using oil again on this one?
Yes.
What difference does it have on paper and transparent sheet for exposure time.
The same exposure time...paper is Cheaper and always available that's why I'm recommending it for beginners...
@@EasyVideos thanks
Sir I would like to know how much time the emulsion takes to dry off , and I am looking to expose the positive to sunlight for 10-12 seconds will this do the job !
Using electric Fan -emulsion dries in about 15 to 30 minutes........yes 10-12 seconds will be ok....
@@EasyVideos sir, 15 to 30 mins drying on the electricfan for first coating and another 15-30 mins drying for the second coating? am i right sir?
if im going to use tulco local, can apply the same drying time?
thnx
Sir salamat sa mga videos nyo.. mdami po akong natututunan.. ask ko lang po sir if san po ba ako makakabili ng murang mga gamit sa pra sa screen printing.. salamat po
JnJ VIrgo at Tulco Screen Printing Supply po ang Kumpleto pagdating sa mga Materials na kailangan sa Screen printing....
@@EasyVideos ahh ok sir.. maitanong ko narin san po ba located yang mga shop na yan.. thanks again!
Hello we are using Water based tulco photo emulsion local. Pwede po bang direct e coat na yun sa screen or need pa talagang e mix sa photo sensitizer ? Sa direction kasi sabi shake and coat lang kaso white siya . 😊
Kailangan po ng Sensitizer....para mag-react ito sa LIGHT...
Ok lng po ba kahit walang salamin or glass na cover inexpose?
Oklang po, pero kung Hindi nyo Mapalapat ng maayos ang Positive sa Screen OK lang din naman gumamit ng GLASS....:)
i have a 250W bulb with a 18x22 screen using diazo emulsion.. i have the word “SEX” above a image of a girl.. the girl only has her highlights (whites) being printed. what would u suggest height wise and time wise for exposure
Nice design by the way...I think you have to experiment to determine the right Exposure Time...I'm not familiar with other brands of photo emulsion...just to make sure....thaks for visiting...:)
Boss Easy , tanong ko lang po ordinary ink tas papel lang po ang pinagpi-printan mo po ng positive design mo?
Yes....
Which color is the school dress T-shirt and what name is it known?
Plz tell me sir
I use Water-based Textile Paints, you can use it on Different kind s of Cloth material...
boss easy ask ko lang if okay lang po ba gamitin yung emulsion na pinatuyo ng isang araw po or hindi na po?
Sa Experience ko po mas mahirap nang hugasan ang Photo Emulsion pag ganoon katagal na sa Screen....Kung sa Madilim na lugar nakatago o may Cover yung Screen baka ma-pwede pa....
hi sir, does the cooking oil just wash off, without leaving any oilfilm on the emulsion?
Yes, correct
@@EasyVideos nice! this method is so awesome and saves money...thank you!
pwede rin kaya sa half-tone and process na ito.
sir,, what about 20wats LED light??
You can do the same Experiment with the 20Watts LED to determine the right Exposure Time........
are you in a light safe enveroment when you are mixing the emolution
It doesn't have to so Dark, you can use light Bulb that emits yellow light because it has no effect or very little effect on the photo emulsion...
why do you not use sensitized emulsion?
You can also use that if that's the available photo emulsion..
Sir Easy. another question po please. pwede po bah dalawang bondpaper para sa positive? kase hindi medyo black ung ink ehh or sa quality. pwede po ba dalawa bondpaper? kng wala ng options.
yes k lang....
which number is perfect???
4-6 minutes for fine detailed design and 6 to 10 minutes can be use for regular designs...
