My experience with 3880, p800 and p600 is that using the front feed option eliminates the pizza wheels.? It is likely that the p900 will do the same. There is no hidden instruction, it assumes that you are loading posterboard. I use a carrier for DTP polymer gravure? (window cut into 2 ply matte board) so that is my default anyway - for film you may want to try attaching it to a carrier as well -because I am pretty sure that the? platen gap automatically adjusts for thick media.

Emne: Re: [QuadToneRIP] FYI for Mac Users

something to consider. I use an old Mac mini i3 running Mojave to print from. It's headless. but I see old Macbooks on FB marketplace for $150.00. You can get one of those to print from. I do my editing on a more up to date computer then access the other Mac via screen share and drag my image over there and print from print tools running off that Mac. It's a lot simpler than having to struggle with getting this stuff to run consistently with Seqouia etc...

I have a question about cleaning/storage solutions.

I've bought PiezoFlush from Inkjet Mall and I've also bought a clear solution from Inkjet OWL. Both offering similar functionality.

I recently found an online doc showing piezo cleaning formula as:

<Screenshot 2025-01-08 at 8.58.55?PM.png>

When I compare to Paul's cb6 base, the above adds glycol, alcohol and colouring. Since Pauls formula adds Edwal LFN as a surfactant, seems like it could be used as for the same purpose?

Paul's formula:
55% distilled water
34% glycerol
10% Kodak Photo-Flo, and
1% Edwal LFN.

Has anyone made their own for storing and flushing your lines?

Roy,

You are a Godsend.

It worked.

But the command for some reason had to be InstallP5300=P900.command. For some reason this printer only shows as a P5300. Then I cut and pasted all the quads into the P5300 file folder, too, and they showed up fine.

The P 5370 is SO sensitive. You have to go through a lot of machinations to make it recognize sheet feed and not cassette or manual. AND position the OHP perfectly so the driver head sees it. Also to push the OHP quite far down in place, do all the selections of paper type, size, etc. in the printer control panel itself, before pressing Print in Print Tool. Otherwise, errors abound.

I also had the usual problem of the top inch of the negative print low density so I assume a workaround is no more than 9 inch image, image 1 inch away from edge, or go so far as to cut and paste part of the image for an inch at the leading edge as some have done (that will be beyond students).

I will be making step by steps to laminate so students will not run into the myriad picky issues this printer displays, but if we can print negs with no pizza wheels I have died and gone to heaven. We’ve kept the two P900s as backup in the lab for busy images that pizza wheels will get lost in, and just have the one P5370. I mean, it’s a BEAST in cost and size, really not a consumer model by any means.

?

Question is I wonder if it really makes a dif using 1440 super, or 2880, or 2880 super? I’m trying 1440 super to see if it’s adequate with some negs I printed.

?

I also will report back if the P900 profiles are perfectly fine or need major tweaking. So far the negatives I’ve printed for new cyanotype and palladium look as I would expect but that doesn’t prove anything until I print prints.

Hi Chris?

Just rename script to InstallP5370=P900.command

?

This will find P5370 printer but use P900 driver.?

No luck being able to install QTR for the P5370.

Op sys attached.

Error message attached.

I’ve named it P5000, P5300 series, P5370, none work.

I’ve re-installed QTR 3x.

I’ve turned on and off printer.

I’ve made sure all permissions are read/write on the folders from Library to quadtone to quads.

Any ideas?

Someone on this list had no problem using P900 profiles on this printer, either, and I do notice the inks are the same except VLM is LM and VM is M…hope that is not an issue.

Michael, you mentioned ?ch printing uv blocking borders on n PS. I used to do this and they worked great for my platinum/palladium printing. For some reason this no longer works. By not working I mean that they borders no longer seem to block the uv enough to achieve a clean border even though I can achieve a paper white within the image. I have not been able to figure out why.
