If the image is not photographically printed the image will degrade, depending on the output system.
You should not use a normal 24-bit or grayscale image. The files must be, either in vector format or at the exact same resolution of the printer, 2400 or 3200 DPI at 1 bit. This is not expensive, but you need to find someone that can print it. Probably you can ask if a prepress bureau can either print directly on photographic paper, or print a negative on film and then make a transfer. What needs to be taken into account is the resolution of the file and the resolution of the output, besides the interpolation method used on them.Ī real test chart is printed on high-resolution photographic systems, which gives crisp lines, up to 2400-3200 DPI. For a resolution-only chart, aka Black and white I am not sure if you could commercially use the patterns of the test chart, but if you understand the idea behind them you can prepare some of your own. If you only want some target to compare, I guess you will be fine with some generic products. If your workflow needs to be standardized, use some tools for the standardization.
It is a bit expensive though, so you can find some other camera test chart options on Amazon, or perhaps find some second-hand on eBay.īut as you want to use them in a showroom. Please google "ISO test charts", or "test charts targets" To my knowledge that one is ISO-12233 "Digital Resolution Still Camera Test Chart".
