I believe someone mentioned an inexpensive site that printed 20x30 posters for around $10. If not, can y'all recommend a vendor who does produce acceptable posters from a digital file?
At that size (20x30) what's the lowest dpi the image should be set at for a reasonably clear poster?
If the image is saved as a jpg, will agressive compression badly harm the final printout?
Currently, my image is at 180 dpi, and is imaged out to 20 x 30. The file size is about 5 megs uncompressed, and about 380 K compressed to the max.
This image is of great sentimental value to a lot of people so your help will be much appreciated.
