Now i don't know if ppi and dpi are basically the same, or wildly different. But i've set ppi to 300 for each exported image. So it should be fine?
I just open the sharpening, click ok and then it's applied?
That is interesting. First the ppi / dpi In this case they are interchangeable. A guide to ppi https://resources.printhandbook.com/page...inting.php but save that for later.
Question. Does the 110mm x 90 mm include the 3 mm margin ? Is the initial crop in a 113:93 ratio or is your 110:90 correct ?
If the Printer uses 150 ppi then you should use 150 ppi and set that in the Image -> Print Size resolution. That ends up with an image size of 667 x 549 pixels for a printing size of 113mm x 93mm. Not photo quality but probably applicable to type of printing material. A plain card or an absorbent art paper is never photo quality.
To sharpen or not to sharpen is all a matter of preference. Going by the above probably no.
This is a 113mm 93mm @ 150 ppi crop and scale. The scale shows at 34% , which is about a low as I would like to go. Open it up in Gimp, check the Image -> Print Size for 150 ppi
Yes, the 110x90mm includes the margin, they told me to just send them 110x90mm images and they'd do the rest. Basically they just scale the image further down by 3mm. The final product is 110x90mm.
If i open up an already exported image and change the ppi, would that be fine or should that have been done before exporting?
