As Szalam asked we really need to know what program you are using to print from. I also have an Epson and once in a while I run into software/ hardware issues some which are easily solved and some not so much. I thought of purchasing a rip when I bought my printer but the cost was beyond the advantages. Is your driver current? I am sure that you are upto date on this so just a question to make sure. Key is knowing what Adobe application you are using....
Thanks for the replies.
Most if not all we print from is using adobe software mostly indesign and illustrator. I know my question is not really an "adobe" question but I figured I would give it a shot. The rip is ColorBurst which came with the EpsonGS6000 plotter we use we have bought updates for it over the years Ive heard. A problem is the software is no longer being supported by tech support and is basically discontinued.
I did reprint the flawed images then 6 of the 7 printed fine with only 1 gltichy with stripes. Then reprinted the last 1 I needed and it worked as normal. I work at a printing/publishing company that has about 60 people and I spent hours talking to our prepress, IT and graphic designer to see if there was something they knew. I checked all they suggested including transparencies and several preflights in adobe acrobat and advanced plugin software as Pit Stop and found nothing. I am a graphic designer but not with many years of experience and this problem was a mystery to every one I shared it with. Im 95% its a problem with the rip but being like a 1/1000 thing I can live with it.
The printed pieces were for car magnets for a customer that several times a year changes what is displayed on the vehicle iwth the exact same sizes/files but different content. I remembered the last time we did this project I had the same problems but the time before that not a single problem. I grilled the designer who did them to see if anything weird in the way it was saved from InDesign and we could not find any problems. As said if problem x was happening every single time in a situation then you can pin down what is going on better but this seems more random and the only thing in common being that I set the plotter to print over 10ft of piece/pieces at once.
Talked to my boss about this in detail and he said he had seen it happen with that machine/rip as I did a few times a year but not consistent enough and not often enough to being able to find the problem. Out plotter is about 4-5 years old and he is looking for a new plotter to replace this 1 with in the near future.
