Resolution greater than the CCD optical rating is simply interpolated resolution, done in software after the 600 or 1200 dpi optical scan. Interpolated resolution is the least important scanner specification. It was useful for line art mode, and only for line art, to reduce jaggies when we had 300 dpi scanners and needed 600 dpi line art. In my test prints, "1200 dpi" seems better than HQ1200, but I can't. find any description in the manual or elsewhere. Brother support says that. - 1200 dpi is true 1200 x 1200 dpi, the best possible but slowest. - HQ1200 is interpolated 2400 x 600 dpi, which does not look as good. In this video, we take a look at the importance of using the correct DPI settings for your sublimation printing.Check out our other videos and blog posts at Neither do I. 300 DPI is just about perfect for prints that will be look at while held in your hand or viewed. As you increase DPI much further you start to meet the point of diminishing returns. Theoretically a 600 DPI is much better than 300 DPI, but you also start to run into the resolving power of the human eye at that point. A 10D images are (assuming landscape): 433.493mm X 288.966mm @ 180dpi. or. 260.604mm X 173.905mm @ 300dpi. A3 dimensions are 420mm X 297mm. The way I learned to upsize pics is to do it in 10% increments. Image> Image Size> Under either Pixel Dimensions or Document Size change the pull down menu to Percent. 100% is displayed. If you have a 4x6 photo and digitize it at 600 dpi, you will be able to print an 8x10 picture at the same quality and without any loss of resolution. For social media sharing or display on websites, you want to keep the image at a low DPI and in a JPEG format. Many social media websites won’t take large TIFF files with high DPI. .
