So what’s the problem? Can you imagine how hard it is though to cut exactly to the edge of the image? Especially as the image can shift a little bit during the run and can even vary from sheet to sheet - especially when digital printing is used where this variation can be us much as 2-3mm. If we printed on a larger sheet then tried to cut a whole stack of paper you might find that the top sheet is about right but the sheets underneath will vary and white edges will show. Sheet 1 Perfect Sheet 2 Image has shifted down & to the right Sheet 3 Image has shifted down Sheet 4 Image has shifted up Sheet 5 Perfect Sheet 6 Image has shifted to the left
