A Digital Printing Network
Sometimes when I'm printing a large sign that might be broken up into 3 or 4 panels the colour changes from panel to panel. for example if I have to print a 12' x 8' sign I send it to versaworks for print as an eps file, I then crop it into 3 8'x4' prints with the overlaps and then rip and print. My problem is the colours print different on the three panels and is noticeable on the finished sign when the panels are put together.
I changed my dampers to the larger size ones but i still get the same results and my printheads are in perfect condition, also all the prints are done in succsesion on the same day and its all done without changing cartridges half way through, I dont print one today and the others tomorrow, so they should be all the same.
Has anyone ever experienced similar or have any idea what could be causing this.
I would troubleshoot by looking at how the colour variations appear and post more details.
Example: Are the colour variations appearing to change vertically or horizontally across the print? Are they darker or light? etc.
A photo would definitely help the pros here help you ;-)
To clarify your issue:
Are you doing the panelling in VersaWorks?
Or are you doing it in your software then ripping and printing 3 separate files?
I am doing the panelling in versaworks, the variations are, for example, a big picture of a kitchen ( one of my customers makes kitchens and wanted to put a big pic of one of his best jobs outside his shop) first panel will always look really good second panel would have a lot less magenta in the print and third would be lacking cyan or blue, not always in that order but thats an example of what I mean by colours changing.
Chip are you alternating top to bottom bottom to top panels? Which color palette are you using? Which design program? Are you bring in any profiles from the design programs?
All I am doing is designing in corel, exportig to versa works and printing. I dont bring colour profiles or anything else in, I just crop and print and let VW do its own thing. It isweird because if I print a really long job, say 12-14 foot by 4 foot everything is perfect, so would something be happening in the rip. I know that temp is supposed to affect prints but my room temp doesnt vary at all really.
It's so where the panels meet they are printed on the same side of the printer to lesson the real limitations of the printer such as tracking, platen temperature, spray angles, ect.
yep, John, sort of like when you install a rug and need to reverse each run so you don't see the seam because of the nap
Makes me laugh. We put down carpet squares in my office last year and practically went out of our minds trying to remember which way to rotate each adjoining piece
Panels are one thing, squares with four equal sides with no perceptual pattern was a whole 'nother ballgame!
