I have been these days printing signatures for an artist book with Piezo K6 inks Selenium on Hahnemuhle Photo Rag Book and Album 220 gsm.
The problem I am having, as it has been documented in some places, is that when I print the back of the sheets, the prints at the back get roller marks. I wait for a day for the prints to dry out, before printing the verso of the sheet. Even like that, the rollers seem to compress the ink of the already printed images, and these marks are visible when the light strikes at a certain angle. Kind of “rubbing” marks where light reflectance is different.
I have looked around, and it seems that this problem has been documented. Too bad I only realized now. Strange that this kind of papers are sold to do something that apparently cannot be done?
My questions now are related to ways or tricks I could bypass this problem. Among them, I have seen some people use a second sheet of paper to protect the already printed back. My question is: Would it be a good idea to use a second sheet of 220 gsm Hahnemuhle Book and Album paper of the same size? Or should I use a thinner paper? If I use two sheets of paper instead of one, should I choose Platen Gap Wide instead of Standard? Should I re-print and calibrate the paper thickness AND paper feed adjustment values? I calibrated them for a single-sheet and prints came beautifully…
The other question is related to how to fix the “protecting” sheet… Can I just put two sheets of paper at once in the printer, aligned but not taped-fixed one to another? Or would that jam the printer? How would you suggest attaching the protecting sheet to the printing sheet?
I would like to know whether at Cone Editions you have gone through the process of using double sided printed paper for publications, artist books etc. I have all the process done and working perfectly… but these roller marks are ruining the whole thing!
By the way, we have realized making handmade books of your projects is just the best way of coping with a pandemic! I strongly recommend you the exercise. Wonderful prints with piezo!
Thanks in advance for your help and keep yourself healthy and creative,
