Settings for UP OHP with Epson SC P7000

Hi all,
Are there any thoughts about Custom paper settings on the P7000 for Pictorico UP OHP? The answers may be the same as those suggested in a similar thread for the Epson 9900 (Recommended Paper settings for Pictorico on Epson 9900) … but in case not, I’d love any info that will help me do a quick setup.
Thanks!

Set the custom paper settings to Epson Glossy 170, Narrow Platen gap. Then do a manual UniD head alignment calibration on the film itself with a loup. It’s best to do that on large sheets or 17" roll.

Hi Pradip.
To what Walker mentionned i would add: perform the paper feed adjustment test where the printer prints a set of squares and you need to choose the one that looks more solid (filled with equally spaced lines) AND DO IT SEVERAL TIMES UNTIL YOU SEE THE 7 VALUE IS THE ONE you choose for all lines. Paper feed adjustment is quite important to nail if you want to avoid micro banding. You might need to perform two custom paper settings… one for roll and another for sheet. I guess the tension involved affects the paper feed adjustment. So if you see problems, think about performing the test for PFA both for sheet and roll, separately.

For most people and for most images full of texture, the micro banding and normal banding might not show regularly… but when you try to print images with big areas of solid and homogenous medium tonality, you realize the limits of inkjet negatives…and minute changes can affect the outcome.

The P7000 is a great machine!

Regards,

Rafael

HI Rafael and Walker,
thanks for your suggestions. I have done all of the above. Printer is very fine-tuned now.
I have (for anyone else using a similar setup) the following configuration/adjustments:
Created a custom paper setup for Pictorico UP OHP Sheet:
Reference paper: Premium Glossy 170
Platen gap: narrow
paper thickness: 1
paper feed adjust: -0.16 (this will vary depending on your particular printer and you should run the “Pattern” routine to get the measurements. You must use UP OHP that is at least 19" wide – I loaded 13x19 inch sheet sideways)
Suction: -1 (I was getting severe roller marks and scratches on the back of the film with normal suction. Reducing to the minimum has helped a lot, but still not full absent. Any thoughts anyone?)

Finally, I ran a manual UniD head alignment. Here too, you will need a 13 x 19 or larger sheet of paper, loaded vertically.

Thanks,
Pradip

Maybe I’ve just been lucky and have not seen the marks appear in the actual prints on various 9900s and P9000s . . .

But backing the film onto a thicker medium and changing the appropriate media type settings may be a way to go . . .

Interesting about not seeing marks on the P9000. Rafael, have you had any marks show up on your P7000?

There is always something eh?

a small update:
I hav reduced the suction to -0. This helps with the scratch marks on the back of the film. It seems that heavy suction around the printer head passage is causing this. -0 does not entirely remove it, but it is almost negligible now.

Hello Pradip. Yes, there is always something, you said it right!
Yes, me too I have a few scratches sometimes, but not visible on the prints. Reducing the suction helps, yes. Interesting to know that you have good results with 0 value…
Cheers,
Rafael
