Step 2
Scan the printed sheet. Scan settings must be 600 dpi and colored scan with photo quality (24bit color depth).

Step 3
Save the image of the sheet as JPG picture. Mind the compression rate. Use a high quality setting to avoid loss of pixel information but mind the file size. The image file muste be smaller than 10 MB. If the file size is too large you can also cut the picture.

Step 4
Upload the image. If you have problems with the image size, do not decrease the image quality or resize the image. The better way to reduce the size is to cut the image.

Step 5
