A 3" by 5" b&w photo is scanned using a HP 4C flat bed scanner at 300 dpi resolution. The file is printed using Corel Photo Paint 5 on a Fargo Primera Pro printer. The print is acceptable at an image size of 3" by 5". I want to increase the image size to 8" by 10". How do we increase the image size without it becomming pixelated? We have tried increasing the scan greater than 100% and scanning at up to 600 dpi without success. Also tried various smoothing routines but we need a very sharp image. Any ideas?
