We always scan at least 600dpi at same size. But after consultation with you we may scan at a higher resolution. For example if the print supplied is small and you would like to show it at a larger final size, we will scan at least 1200dpi.
For example if your image is a typical old 4×3″ (100x76mm) print then it is very difficult to create a really big print. A screen can show the same quality image at a larger size as screens are 72dpi (Mac) and 96dpi (PC) while a printed paper image needs to be 300dpi at same size.
What do we mean by same size?
It simply means that if an image is physically 100mmx100mm, scanning at 300dpi will allow ithe scan to be printed at high quality at 100mmx100mm. Any increase in final printed size will DECREASE quality.
Screens can show the image successfully at much larger sizes.
WHAT DPI SIZES MEAN FOR YOU.
1200dpi or higher allows us to provide you with a file that can be printed on paper at A3 size (420mmx297mm) or (16”x12”). These scans can be used at 6000x4000px size on screens. That will show beautiful images on huge TVs or 27” Apple iMac monitors.
600pdi allows us to provide you with a file that can be printed on paper at A4 size. These scans can be used at full size on computer screens.
Our scanner is a professional scanner with a very high density rating. That is more important than dpi or any other measure of resolution. It also has better optics to give a clearer result as it allows the scanner to see into the dark areas better.
