Registration problems

Posted on Fri, 3 Feb 2006 at 19:33



Hi,
As a fairly new screen printer, I'm still using a 'standard' inkjet printer to produce my images onto transparencies(acetate). The problem I have is if the image requires more than one colour (and therefore more than one screen), I cannot get the seperate images to line up. I have created 'registration points' on the images, but when the computer prints them (its a good reliable printer, printing from photoshop) the images NEVER line up...they look the *same* but there are minor differences in alignment. Any suggestions?
Many thanks

As long as you have three registration points you should be able to dial your image in correctly. However, off contact and inconsistent print stroke can make your registration look off even if you are dead on.

It's a pisser ain't it! the same thing happens with laser printers. The problem is in the heat system, it shrinks the film.
There are films that have paper backing or thicker film, it will needless to say be trial and error!

i have been doing seps since a long time ago here in mexico.

first one question how reliable is your printer what kind of priter do you have?

for me epson 4000 is a best choice

photoshop is not the problem

your printer maybe is the problem but

normaly this kind of troubles are in the film, try lawsons film i tried 5 different brands and this one was the best for me (i tried fast pos too)

if it doesnt work the problem is the track of your printer may be you need some adjustments there or may be you need a better printer

about laser printers: yes it is true the heat shrinks the film and i wouldnt recommend this printer system but anyway if you have one, you can help to avoid this problem sending a blank print on the films and then print on this preshrinked film your seps (i said help to avoid, it doesnt works always) but the most of the times works well

When I do posters (19"X25") I have a bluprint shop plot my positives for me off of PDF files. I had major problems with reg marks not matching up...mostly vertical, horisontal ones are always close. I got a tip off another site- let that machine cool down between prints. Might need to sweet talk the guy on duty but it does the trick. My last set was for a 6 color print...all 6 were spot on!

You didn't say if the problem was in lining the film up onto each other or if the problem was on press after you had made the screens.

If the registration were on a film level - never use film on a roll as the drag from the roll will cause the film to feed differently every time as the roll gets smaller. Also static electricity on the roll can cause the drag to alter from sheet to sheet.

If on press, I'd look at your tension levels. You need a matched set of screens, all with equal tension to eliminate the registration variable. Feel free to write or call me with additional information and I will try to walk you through a solution.
