Hi,
im trying to get a better understanding of offset printing technology but currently struggle to find a "nice" explanation of gapless vs. conventional printing ( a topic I heard in an interview that unfortunately didnt go into detail - the Goss Sunday was mentioned as an example) and hope you can let me know if my current understanding is correct or point me to useful resources:
So far I have gathered that usually blankets are put around the cylinders - the fact that they have to be attached in a cylinder gap means there are vibrations as the cylinder weight is not perfectly distributed. gapless doesnt have this problem as a kind of rubber sleeve is put over the cylinder. is this correct so far? also is this essentially the same as what is meant by "seamless" on some sites?
The issue I don't understand is that apparently the gap using the conventional way is only 0.2 inches or so. as the paper needs to be cut anyway between the different printed pages, are those gaps made by the conventional system really that much of an issue? or is the problem that its not possible to create "endless" images such as christmas wrapping paper?
many thanks in advance

I have another questions about how paper type affects machine built but i guess that should go in a different post
