CMYK colours

Hi,
I'm ready a lot about screen printing but can't find straight answer for one question:
Can you mix colours by applying 4 colours without drying in-between to get full colour print (similar to colours mixing inside jet printer) ??

Also what's your opinion on screen printing vs versacaam for fashion t-shirts purposes ??

[Ian M]

Kris, it all really depends on what your printing. If it's T-shirts then yes you print one colour on top of the other straight away as on a carousel.

If you were printing on things like plastics etc then you would need to dry each colour before printing the next.

[Paul]

yes you can. wet on wet

Uhm....process work....just love process work!

Calm down dear it was just a bikini :biggrin:

[Justin]

Not the bikini that excites me, just the printing process

[Paul]

printing proces is great! give you lot of satisfaction after you develope your screens etc...

Screen printing always fascinates me - I just haven't got the room to even try it out

Always made me think though (for anyone with screen-printing knowledge) if you have a multi colour design and are doing it wet on wet then surely there's some transfer from the t-shirt to the bottom of the screens? This would then transfer onto the next shirt when printed?

Unless (just thinking) it doesn't matter as the process in the same colour screens (if you know what I mean? - it's been a long day!)

This has got me excited about getting back into screen printing, watching some of the associated videos along with the one Paul showed I used to work for a screen printer many years ago but only dabbled a little on the actual printing side. I've been toying with the idea of getting a 1 or 2 colour carousel set-up....like you say, it's just having the room!

I've watched this a few times and have done full colour work on card/plastic and as Ian says - its one colour, dry, then the next and so on.

For T shirt printing its wet on wet but as Adam mentioned there's pick up of the last colour on the next screen. If there's no colours touching you can get away with it - if colours touch (like full colour work halftones) you'll get the inks blurring, smudging or even, if left, mixing and changing colour on the overlap. I've never used trichomatic plastisol (for full colour work) on T'shirts but the principle is the same so you would get pick up. This is why we sometimes use a flash dryer, inbetween prints on overlaps, to make the ink touch dry so it doesn't transfer to the next screen. What it doesn't show you is for every 10 ish prints each screen may have to be cleaned underneath to stop the transfer.

Still looks good but he seems to have a moire on the models legs.
