Help printing gradient from Photoshop

Help printing gradient from Photoshop

2018-09-07 by Dwight Lindsey

Hello all:

I’m new to the list and I’ve got a simple goal that I’m having trouble with.

I’ve made some gradients in photoshop. I’ve got linear gradients and radial gradients. They look beautiful in Photoshop.

I’m having trouble printing them as smooth gradients.

I’m using an Epson SureColor P800 printer with the OEM Epson Inks.

When I print directly to the printer from photoshop, I don’t get smooth gradients.

I had hoped that QuantoneRIP could help, but when I make a TIFF, which looks good, and print it with Quadtone RIP, I get pretty much the same not-smooth-gradient.

I’ll be grateful for any help getting me pointed in the right direction to solve this.

Thanks!

Dwight

Is file 8 bit or 16 bit? Printing at 1440 or 2880?

JPGs are 8 bit. Printing at 2880.

That is probably the issue, needs to be 16 bit at creation time and print out as 16 bit. Don’t covert to 16 bit, it will not help. Stay away from JPEGs too, bad file format, destructive. The printing DPI looks good. Also make sure you have no printer issues, check the nozzles and alignment.

Image is grayscale, 8 bit.

I can easily make it 16 bit, but the not-linear-grad issue is not subtle at all . . . I wouldn’t imagine that the 8 bit 16 bit issue would result in the problem I’m having . . .

But I’m hear to learn and glad for any suggestions.

I created a 8 ½ x 11 gradient, 16 bit, Greyscale.

Saved it as a TIFF with no compression.

Now I get an error message “Unable to create TIFF Bitmap buffer”.

What to do?

Thanks!

Are you using a standard QTR “profile”? If so have you run the linearisation script so that it works with your printer?

The fact that you had this error message suggests that you're on Windows. If you scroll down the posts in this group to around 24-25 Aug you'll see that I had the same error message. I didn't ever solve it directly. It came and went several times and seems to have gone away. It seemed to be related to the number of pixels in the image file rather than the Mb size of the file

In relation to your initial problem of unsmooth gradients, I'd be more inclined to suspect your colour management settings than the file format and bit depth, although creating and printing a 16 bit uncompressed TIFF can't hurt. If you manage to get past this error perhaps you could share your workflow in more detail and esp your CM workflow & QTR settings. QTR should be able to print a pretty good gradient.

Hi Brian:

Yes, Windows 10.

Since that post . . . in between other real work . . . I’ve been going through the curve generation and linearization routines. So far without good success. I don’t like the way the 21step prints look.

I don’t have a densitometer. I’m printing on transparent film and my scanner doesn’t really do that . . . so I’m struggling.

I’ll keep plugging at it. I don’t fully understand what I’m doing yet, but I’m further along in the process. From long experience with other technical puzzles, I’ll get this, after a few days more struggle.

If there’s anyone in the Los Angeles area (I’m in Lancaster, NorthEast of LA) who’d like a consulting gig helping me figure this out . . . I’d like to talk.

Dwight

I'd missed the fact that you're printing on transparency. I only print on paper. There are number of dig neg practitioners here who may be able to help.
