Originally posted by demp10 I have a K-7 and an EPSON 7600 printer (24" wide) and routinely print 24" x 36" on EPSON Canvas with excellent results (for gallery exhibits).
At that size, the image resolution is about 130 dpi and I use a separate printing/resampling application to upscale the images to 360 dpi before sending them to the printer which prints at 1440 dpi.
If you plan to send your images to an outside lab for printing, you should upscale them to their specs (usually at 300 dpi) using the best resampling algorithms your image processing software provides (most likely bi-cubic).
Thank you demp10, great info. I usually send my pics to outside lab, and I use Photoshop to keep my prints at 300dpi. I am really not that good about all the calculations, but according to the link that psychdoc posted
"The maths is pretty easy when trying to work out how big your canvas will be if printed at 100 DPI:
2000px x 1000px image = 20” x 10”
3560px x 4920px image = 35.6" x 49.2" "
DO you know how it would affect the size if it was printed at 300 dpi?
I try to keep everything at 300 dpi, so I am little confused why they show examples of 100 and 50 dpi. Is that because of the lower quality?
Thank you.
