I resize to the destination size and DPI (360 for the Epson, 300 for my HP color laserprinter) and then print at that native DPI to keep the print driver out of the resampling pipeline. Just another function of Photoshop that I do *not* use anymore thanks to Gigapixel. I used Photoshop's resampling in the past, but Gigapixel AI (up to version 4.2.2) is perfect for these artificial plans and invents lots of useful details (plus perfectly rounding aliased lines). The original images I am printing out include grid-lines that are supposed to be 1 inch apart, but the source images are smaller than the output size and even compressed (usually being part of a PDF). I do sometimes use A3 and A2, but rather occasionally. Also think about 300 g/m² photo-quality paper costing next to nothing compared to bigger paper. Think of splitting a large architectural CAD drawing into smaller DIN A4 part where the rooms on the drawing dictate where to crop each smaller print. So printing the whole large plan would reveal all at once (and need a larger printer) and printing poster-tiles would cut the content at the wrong parts. I am printing plans for private table-top gaming where only part of the plan is revealed during a game.

RIP software is more expensive than just keeping Photoshop for many years to come and even more overkill for what I am doing with it. Properly set, the RIP will know how to compensate and size the small cropped image area from the large image area.Ĭould you elaborate what you mean by "size compensation"? Keep in mind that this is not a large print that is being looked at from a large distance, it is many small prints that are looked at from a close distance (0.3 - 1 m / 1 - 3 ft). (Usually unnoticed at small print sizes.) This size compensation control in critical not only for size but also print quality. You will notice a particular setting for both width and length size compensation which is practically always necessary in order to produce the print at the expected final large format size. With some experience, you might learn how "print dots" are ultimately formed from "image pixels" and how various transformations may affect your seemingly judicious up-rez efforts making them superfluous, especially at the somewhat long print length you're after. Look into Onyx or Caldera RIP software which will drive the printer fully. Going for the printer's native DPI then is just the icing on the cake and makes sure nothing else messes things up (even more so when printing borderless). But the upsampling done by Gigapixel is a night & day difference compared to other means.

Until then I will have to stay in the subscription plan, mostly use only a single function of this powerful software and hope that the print dialog bugs get sorted some day (workaround is to flip portrait/landscape back and forth). I have yet to find a software other than Photoshop that does. But it does not allow me to conveniently and precisely crop the image content, especially not for "mass" printout. Qimage offers a crop mode, like many other programs. With PS it's as easy as: Load large image (as in inches/cm), open print dialog, print smaller crop out of the larger image that precisely aligns with image content and neighboring prints. But that would not solve the original problem of looking for an alternative that should not be much less convenient and precise to use. Using a lower image DPI would decrease file size and thus mitigate 32-bit memory restrictions, of course. I am sure that using a reasonably lower DPI would work for my purposes (like half native DPI), especially with the laser printer. Now there’s some question of where and how this data gets resampled.Īnswer above starting on page 2. Well, the printer does resample to its native DPI on the fly, but likely only using something easily calculated such as bilinear. Quote - then print at that native DPI to keep the print driver out of the resampling pipeline.
