You are probably already doing this, but you need to make sure you have a custom media type defined and downloaded to your printer that has a 12 x 16 inch size. You have to have the same media size picked on the printer’s control panel as you have in Print Tool. Any mismatch will print misaligned. IOW, the software will not override the media size selected on the front of the printer.

Hi folks – this is my first post.? I’m just now learning DTP photogravure and platinum palladium using digital negatives.? I’m working with (against) an Epson P900 with updated firmware via QTR with Print Tool as a front end and Piezography P900-Pro.? Quad files are from the two classes I took on these processes.? I’m in the final steps of setting up a home lab starting with DTP and heading to PtPd as soon as Bostick and Sullivan works through a chemical backorder.
?
My prints to DTP are not centering, even though all the various settings seem to be ok.? I’m mounting a Tyobo KM43 plate (8 1/4" x 11 3/4") onto a 12x16 poster board.??After two days of swearing like a 19th century sailor I got that to work consistently on the P900.? Both the physical plate and the image are centered on the carrier board.? If I print a PDF from QTR I get an image that is correct (I've attached a copy of that.)?
?
When printing to the plate however the image offsets, printing correctly along the 10” side but with a 2 5/8” bottom margin instead of the nearly edge to edge print I’d expect.? The image is somehow cropped at the top – there is no overprinting onto the carrier, just missing image space.? So for an 8x10 image I’m getting about 5.5x10.?
?
The printer is set up as QuadP900-Pro Bonjour and is connected by USB.? QTR mode is 8 bit (the file is 16 bit tif), curve 1 is a custom quad file from a class, paper feed is front poster board, res is 1440 and speed is unidirectional.? On print tool everything is centered and sized correctly.? Management is set to Print-Tool Managed.?
?
The images attached are a PDF output directly from Print Tool and a terrible iPhone photo of the plate after printing.?
?
Super frustrated.? Any advice is warmly welcomed.<PDF from QTR_1.jpg>
