Nice video mate and spot-on as usual top technician, great information and if everybody listen to you we’d have less breakdowns with stencils and Marc much better prints
Absolutely wonderful sir. This is the kind of honest detail I am looking for in a video. Thank you for time and efforts.
thanks for watching! we appreciate the kind words
Screen covers come with rubber covers. Keep them on them when not in use.
great tip!
I use a 400 watt metal halide bulb. a 20x24 screen takes 12-14 minutes to expose depending on whether the mesh is dyed or not. I'm using chromaline udc hv dual cure emulsion. I usually post harden my stencils, this makes them more durable and easier to reclaim. The bulb I use is a lamp for growing plants which does emit enough light in the uv spectrum to cure the emulsion. Led seems like the way to go with smaller format screens being more efficient than high intensity discharge lamps. In a high production setting exposing dozens of screens per shift a commercial exposure unit is the only thing that makes sense.

My $40 wooden box with 4/4' flourescent bulbs has worked great. I was actually hoping he would go into exposure times for each light source but I was wrong.
@@JenniferBrown-y7j exposure times will vary based on emulsion type, artwork, mesh color, etc. so there’s not just one general exposure time for everyone. We have a different video showing how to determine your exposure time using an exposure calculator
Great video- what is a good starting exposure time for capillary film using a flourescent tube tyoe of exposure unit (with neoprene Cover and vaccum pump style). I dont have an exposure scale- just looking for a ballpark starting point. Using posi-film/ velum or mylar printed with an inkjet.
@@duragodraphics what is the thickness? We have some recommendations on our user guide: www.ikonics.com/wp-content/uploads/2017/06/2021_ProCap_UserGuide_CHRM-1.pdf
What is the typical shelf life of a capillary film unused?
@@DigitalLiquid we generally say that coated, unexposed screens can be stored up to one month in a clean, dry and completely dark area
I put up a very bright LED work light (suspended) over my quilting machine / frame. It was not expensive and was from Home Depot. I prefer using the sun, however living in Oregon sometimes precludes that method. I discovered that the bright light over my quilting frame works very well. I don't believe a "box" is a useful investment, as it is easy to place the screen to be exposed with the image and glass on a black piece of felt in a box lid (like a paper or bankers box for portability) and with a piece of thick cardboard "lid" or cover to protect it from light except when exposing. I place the box lid / exposure "sandwich" on the quilt or whatever I happen to have mounted on the quilting frame (a table would do) and sometimes elevate it a little more with a portable footstool or box. With my iphone timer running, I uncover the glass/emulsion/black felt sandwich for the needed time, then quickly re-cover it with the cardboard sheet, then pick up the whole thing and take it to the kitchen to rinse. It works great and is very affordable.
@@kthybrown007 thx for sharing!
Have to hold 4 point type. What is the lowest thread coat with capillary film that can be used? Thank you!
@@LikeTektronix what thickness? We have some recommendations on our user guide based on thickness of the cap film www.ikonics.com/wp-content/uploads/2017/06/2021_ProCap_UserGuide_CHRM-1.pdf
Might want to say under 40 lb. air pressure. 40 lb. and up will blow bubbles under a human's skin... One does not want air bubbles in the body.
@@LikeTektronix good point!
great concept except for the $100K price;(
We do offer financing options as well
Right ta, so curious about this. I just want to set up a couple of screens to print on my own clothes, I'm not starting a business, looking at people calculate exposure times etc I just thought it was too hard especially as I have a brain injury and my maths not there anymore. My question is if using the sun is there a way to tell by looking at the screen or how it feels to know if it's been exposed long enough or is it the case you just have to trial and error it to find the right time?
Trial and error, but you can do a step wedge test. We have a video on that as well -> chromaline.com/exposure
Very Good
thank you :)
Trying out the hydro x emulsion !
@@chromalinescreenprintproducts I love it . Wish I’d bought more at once!
Thoughts?! Let us know how it goes!!
great tips.
thx!
Thank you for the very helpful video! I have a few questions that I hope can be answered. 1) When washing out emulsion on a screen after exposing it, can the screen be exposed to UV light in a non-light safe room? The only place I can put my washout booth is in my backyard under a shaded patio area. It is by no means light-safe, but it is very well shaded with shade tarps on all sides. 2) What is the name/brand of the screen holder equipment at 5:06?
If you have a fast-exposing emulsion, this will most likely be a problem. If you have an emulsion with wide exposure latitude you may be okay depending on how long washout is taking you. We definitely don't recommend it, but it may work. We built this screen coating holder ages ago, but if you search for "wall mounted screen coating rack" or something similar, there are options available online to purchase.
So spend $800 is your answer..NOT
We also did a video on using the sun for exposure
Well in screen printing that's nothing. I was a DIY person. Tried to cut corners all the time. Built a exposure unit. Times where everywhere. Brought a rxp converted it to led and now get 20 second burn. This made a world of difference. Next was the dry cabinet. This seemed to give so much issues. It was a hit it miss. Ran thru so many screens being not fully dry and burning issues. Spent the $3600 and got the dri-vault when I say big difference I mean big big big big difference. I can dry 10 screens in as little as 8 minutes if I'm pre heating the unit.
@@elevated-apparel couldn’t agree more!!! 🙌🏼
Should be able to expose the screen for 45 seconds - 1 minute if it is a dual cure emulsion! Also helps if you put more pressure on the glass thats over the film. Have to think more like how a vacuum system works with adding pressure.
thanks for the tips Glen
I am working at the screen department and I am responsible for making screens. I am trying to master applying capillary films to the screen. Our capillary films are different and what is that tool you are using to apply on the screen? I need that lol
Do you mean the scoop coater? Or which tool are you referring to? We also have some videos dedicated to applying capillary film, so check out those as well!
great video, i just started printing and use chroma blue 🤝🏽
we love the blue! thx for watching 👍🏼
lol
Great information. Can you do videos on the full line of products? As a customer, I noticed that rebranding and/or replacement of a lot of products we used from you chemical line.
Yes definitely!
how much this machine cost?
They start around $80K but please contact us for a quote because there are several model options chromaline.com/contact/
Thank You sir..i learned a lot
No problem!
THANK YOU!!!
No problem 👍🏼
I'm using a cheap growllight for a certain emulsion and it works perfectly. It also shortens expo time compared to my old expo unit with fluorescent on it.
That’s great! DIY setups definitely can work when the proper testing is done 👍🏼
Great tips, needed this 15+ years ago lol
Glad it was helpful! :)
Great video I wish they just would not be so expensive. For you have a good deal let me know and I will buy a pack.
:)
A couple of years ago, I had an emulsion rep tell me I should be using the sharp side of the coating trough for 195 mesh screens and higher. This is because those are typically the screens we use for gradients and thinner/dark inks. His argument was you don't necessarily want to lay down as much of an ink deposit for a gradient, or even a dark ink (like black) as you would say, with white ink on a 110 or 156 mesh that was coated with the smooth side of the though. We use a dual cure emulsion. Did that rep send me down the wrong path? We fortunately haven't had any issues using the smooth side for 156 and lower mesh screens and the sharp side for 195 and higher mesh screens.
Sounds like it's working for you!
Can this Technology expose tiny Half-Tone dots and or Gradient shading? Also I need to burn screens the up to 170cm in length by 40cm.
Yes, the LTS works great for high detail work
Do You Produce Burnt Screens for Customers? I need some Screens made. Cant afford the Chromaline System Yet. I'm just an Artist.
We do not burn screens for other people. Check with your local screen printing shop!
15 second looks best. Look not only at image itself but the background area around it. 5 seconds dissolves in water jet, 25 seconds has blocked overexposed thin lines, 20 is way too close for comfort, that's why 15 seconds is the best overall compromise. 10 is too close to underexposure. May work at the beginning but won't last.
thanks for the feedback!
you made a whole list of lights that wont work.. but didnt name a damn thing that IS good to use.
Many of the ones mentioned will work, it just depends on what wavelength the light source is and what emulsion you are exposing. If you want a specific light source, we recommend the Quick Image exposure table top unit, or the LTS laser-to-screen auto exposure for larger shops.
Good job and well done
thx!
Great video! 🙌🏼
Thanks!
🔥🔥🔥
Thx for watching! ☺️
Thanks! I haven't tried screen printing yet but will do so soon
Let us know if you have any questions! 👍🏼
so is a metal hallide bulb out of something like a Douthit exposure unit compatible with Chrmoalime. What type of emulsion is Chromalime, we just switched to it
Chromaline is a pure photopolymer emulsion designed for humidity resistance and plastisol ink. Yes you can use the Douthitt unit to expose. Just do an exposure test to find out your exposure time 👍🏼
Where do you get your pre coated screens from I would think since your using a laser they are a metal mesh right?
No, they are not metal mesh. They are normal mesh screens that we coat ourselves using Hydro-X Z-1 emulsion.
@@chromalinescreenprintproducts Why don't the mesh tore apart.. What is different in xtool screen printing laser and your laser.. For comparison please explain
@@niteshkumar-qc8nq I am super new to lasers but I am going to guess the power settings and or frequency of the laser will play a huge part. I have seen a gay laser on to his hand with the right settings
@@niteshkumar-qc8nq our laser is not removing anything, we are just using the light to expose our image onto our screen, then we still take the screen to a washout booth to finish the screen
Where can i buy the textile film or capillary film at a reasonable price to make just the stencil itself with putting it on the screen ? Thank you
We sell capillary film direct on our website, or check with your local screen printing supply shop depending where you live
Thank you
No problem 👍🏼
Does this only work with sertain emulsion type/brand? I jave ecotex tex blue textile photopolymer emulsion
We’ve only tested our own emulsions, but it should work. You may need to play around with exposure time depending on how wide the exposure latitude is on that emulsion.
It works with Speedball emulsion.
ما المغرب هذه الفكرة اعمل بها منذ 20 سنة المشك هو في الكتابة الرقيقة احتاج لمرتين او ثلاثة للحول على النتيجة
What type of scrub brush are you using? looks alot softer than the hard brush im using.
Just a nylon brush 👍🏼
Xtool coming yo. XTOOL COMING!
lots of fun to be had with that laser engraver
@@chromalinescreenprintproductsDo you think the XTool will be able to expose a normal mesh screen? I believe they are advertising a metal mesh on a precoated screen.
@@DSDCustoms probably not
Thank you very much for your video and clear explanation👌! I have a question, what does the time we give to development depend on? And does the screen number have anything to do with the time? I'm planning to reveal a small logo with thin letters to use with water based ink. Thank you!!!
The time to develop in the sun will be dependent on which emulsion you are using, so you will need to do your own exposure testing to see what works best for your set up
led es la mejor opción
As long as it is in the correct wavelength!
@@chromalinescreenprintproducts es correcto, hoy en día el led uv se puede fabricar en la longitud de onda que necesitemos @chromalinescreenprintproducts is correct, today UV LED can be manufactured in the wavelength we need
I have NEVER had a positive stick like that. I have had my business for 35 years. Seems like you didn't let that emulsion dry long enough at all! Weak...
Clearly u didn't understand the point of the video...
Lots of factors to consider in a screen printing shop, each shop is different.
Are you sure this has to be done *every* time? We use a high-pressure jet which seems to work fine. Maybe we need a lower pressure jet like the one you have, and use some of this stuff. also - what screen types is this stuff suitable for? thanks.
Yes, we recommend it for every screen to eliminate many other issues in the screen printing process
Dang!
