QTR-Quadtone RIP

I ran into a problem last year when printing large file sizes with PrintTool and QTR. The print queue would start and then get a "filter failed" error.

These prints were 32x40 or 40x50 at 360 ppi from 8x10 drum scans. I first ran into this problem when making smaller test prints with letting PrintTool downsample to 8x10-16x20 at full resolution. I temporarily solved that problem with the smaller test prints by first downsampling to 8x10 at 720ppi in Photoshop and then printing through PrintTool. Then, I was able to make the 32x40ish prints at 360 ppi just fine. Now I'm making 40x60 prints with someone and we are consistently getting the "filter failed" error on two different computers (both running Mojave). We still had the same problem with the smaller test prints of the full resolution files but resizing to 8x10 at 720 fixed that. It is just making the big prints that are the problem. I don't think it can be a files size issue because these are about 500MB and I just printed an 800MB file without a problem last week (however it was a P9000, and not a 9900 or 9880).

Any ideas?

How much ram do you have? PrintTool rips to PDF so if your ram is low it can hit a limit. I’ve seen this when printing on the 11880 at >60x100” and less than 24GB ram.

Best,
Walker

Print-Tool is 64-bit, at least according to MacOS System Info.

PrintTool gets up to about 1.15GB in activity monitor with the print queue showing incoming until it hits the filter failure. I tried going down to 8-bit, and printing through Photoshop as well—still nothing.

I was able to confirm it is definitely a QTR problem and not a problem with PrintTool by printing the same problem image outside of QTR just fine. The reason I mention the qtr update to 64-bit is the monthly Mojave warnings about the need to “contact the developer” when the underlying printing functions are called or when opening curves in curve view.

We were able to get a computer booted into High Sierra and the didn’t have the problem with any of the large files we were working with so it is definitely a Mojave’s problem. I’ll try to recreate it tomorrow and send you more details. I was just in a little bit of panic mode because someone flew me out to work on printing with them and got totally stuck on day 2.

I will be installing the Catalina developer beta tomorrow too and can test stuff on my end if needed.
