IMAGE TO PRINT

(4 posts)

    I have an aerial photo that was scanned from the negative at 800dpi and now want to print some large prints at a local photo shop.
    They have a large format Epson Printer and I will get them to print at either A0 or A1.
    The image will be cropped to a square size and fitted to the maximum width of the paper.
    As the original is too large for them to handle (180mb) I want to do the 'spade work' and give them an image or PDF on CD.
    The aim is to obtain as much detail as possible - the digital image has a lot of very fine detail.
    I'm unsure what resolution to use? Do I just place the image on an A0 or A1 sheet in Canvas, crop it and save to PDF? This is how I would approach it, but knowing precious little about the output side of Canvas I would appreciate a few tips.
    The client also wants some overlay of the property boundaries and maybe other line work. Wanting smooth lines when rasterised help here is also appreciated.

    Hi Richard,

    I think 300 dpi is good enough, even 144 dpi maybe also acceptable.

    The more dpi, the bigger file size will be for the resulting PDF file. If you use "lossy JPEG" as the compression method, this will also save the file size. Image quality may suffer a little but not much.

    Hey Richard S,

    Since you need fine detail especially if a vector overlay is put in play, I would suggest increasing the dpi to 1200. I use that for professionally printing when I need a lot of detail.

    As for your document, I would suggest an illustration document set at the output size required. Align your graphic to the center of the page. create a PDF. Also remember to output to a high dpi. Test different output resolutions to see which gives better quality. Since the image is quite large, be patient.

    thanks for these, I'll play around and look at the results in small print before going to real thing. This isn't my sort of normal work so was really out of my depth here.
    regards
