im from germany, i have an epson R2880 and have just started with fineart printing.
now i have read many different advices about what resolution to send to a printer.
i read that for epson you should not upsample an image in photoshop if the native resolution is over 180 PPI.
because the printer will do a better (or equal) job of upsampling the image and that way you don´t have to send as much pixel data to the printer.
michael reichmann said something like that in the LL from camera to print video too (coming directly from the mouth of the epson chief engineer).
now i have just read an article from jeff schewe, and he wrote the exact opposit of what is said in the video.
jeff schewe writes you should upsample... for example 256 PPI to 360 PPI or 600 PPI to 720 PPI.
on other places i have read too, that it is best to send images with the native epson printer resolution of 720PPI, 360 PPI or 180 PPI.
how i understand that, i should resample the images in photoshop so that the image has either (exactly) 180 PPI or 360 PPI.
but imo every unneed interpolation should be avoided? not?
so is it realy better to resample a 600 PPI image to 360 PPI?
or should i upsample to 720 PPI?
lets say i have an 4552x3071 pixel image that i want to print at 13x18cm.
this image has a native resolution of 600 PPI at 13x18cm.
if i trust some of what i have read, i should downsample the image to 360 PPI (2551x1843px).
that can´t be right? why should i throw away all the data... is it really not need by the printer for the maximum image quality?
i hope i made it clear what im after.... even with my broken english.
i have seen the video tutorial from LL, a friend bought it and that is why i come here to ask.
