Look for the file format options at the bottom of the Save As window. Save as (File > Save As…) a TIFF, EPS, or PDF. TO FIX:Open the PNG (or GIF or JPG) file in Photoshop. Do NOT use PNG, GIF, or low-resolution JPG for print (use only for web). Acceptable formats are: TIFF, EPS, PDF, and JPG (so long as they’re high-resolution). Replace the low-resolution image with a high-resolution one. TO FIX: Increasing the resolution in a low-resolution image will NOT solve the problem that will result in a poor quality image. Usually printers will allow a 10-20% range above and below the 300 ppi to ensure quality results. Image print resolution is lower than the optimum 300 ppi. ![]() Open the CMYK copy in Photoshop, change the mode to CMYK (Image > Mode > CMYK color). TO FIX:Copy the RGB image and rename it, adding “-cmyk” to the end of the original name (FileName-cmyk.tif). See Define Profiles… and add a new profile as needed. I’ve defined my own preflight profile to include RGB images as a color space that is not allowed. Some printers may accept RGB images, so it’s important to ask them about this.
