You are aware that if you simply upscale an image to this ammount of pixels (24'' x 36 '' at 300dpi => 7200px x 10800px) you wn gain more definition at the corners if you start with a low resolution image, aren't you?
Also, the JPEG file format is no tmeant for file art, and it will create the artifacts as they are shown - it is better for colored pictures only . Save your images as "png" instead. (Saving as JPG and afterwards converting them to PDF won't do - you have to save as PNG from the program where you draw the lines, and never transition them through the JPG file format) On 24 February 2017 at 13:20, 21stDigitalBoy <[email protected]> wrote: > When printing engineering/architectural prints at 24" x 36" the prints show > pixelation around all of the lines.
