Recommended File Types
.tif Save files from Photoshop or other imaging applications as flattened (no layers) .tif with no compression.
.jpg Save at high or maximum quality setting (minimal compression).
.pdf When saving to .pdf, made sure downsampling is turned off and there is no bitmap compression for the best quality images. Include all fonts and do not allow font substitution. You may use high quality .jpg or zip 8 bit compression to decrease file size.
Other Supported File Types - requires manual submission and extra processing time.

.eps
.psd
.bmp
.qxd
.cdr
.tga
.pcx
.doc
.xls
.ppt

Files from Illustrator, Photoshop, Quark, Corel, Excel, Word & Powerpoint may be submitted for output however these file types often require additional setup time and charges. When possible, check first to see if your application allows saving in one of the recommended formats above.

If you need to submit a file from one of these applications in it's native format, make sure to include all fonts and any other embedded files. Complex projects with multiple files and fonts may need to be sent to us with all files compiled into a .zip or .stuffed file, or on a CD-R.

For best results and speed, always see if you can EXPORT or SAVE AS from your program to one of our native supported formats above (.jpg, .tif, or .pdf).

For normal quality output *, your original file should have at least 75 dpi resolution at 100% of the output size. This is also equal to 150 dpi resolution at 50% of the output size and 300 dpi at 25% of the output size. Use the chart below to determine the optimal original file size, dpi and total pixel dimensions for the desired final output size.

Example: If you want a final poster size of 24 x 36 you can use the charts above to determine that the file you submit to us should be 6 x 9 at 300 dpi (25% of 24 x 36) or 1800 x 2700 pixels for normal quality. For high quality it should be 12 x 18 (50% of 24 x 36) at 300 dpi or 3600 x 5400 pixels.

2. Go to our ORDER page and start the upload... The best way to order is using our regular order page which allows you to directly upload a .jpg, .tif, or .pdf up to 50MB in size. Our system will then analyze your file for quality and aspect ratio and walk you through adding the image to your cart.


3. Stuff or Zip your file(s) for uploading or emailing. If you are an advanced user or have very large files, you can use our advanced order system or send your files to us with the manual upload tool. If you are manually uploading or emailing your file(s) to us, it may help to .zip or .stuff them to decrease file size and speed up the transfer process. You may use any popular program that produces .zip, .sit, or .sitx files.
