| Jun 13, 2017 at 22:47 | comment | added | Billy Kerr | @user2357112 A lay is an edge (sometimes a front/side lay) to which the sheet of paper is pushed or pulled to register the sheet in the same position each time. Sometimes a side lay moves mechanically to push the sheet into position, other types are a kind of stroker lay which pulls the paper into position. There are different types depending on the kind of press/manufacturer. | |

| Jun 13, 2017 at 21:17 | comment | added | user2357112 | What do you mean by "mechanical lays", and how do they provide better registration? Google and Merriam-Webster didn't turn anything up. | |

In sheet fed offset lithography, it generally requires two passes through the press to print both sides - unless it's like a duplex web offset press which can print two sides at once, such as those used for printing newspapers. | |
| Jun 13, 2017 at 19:45 | comment | added | melkimx | Thanks @Quint. I imagine that it must be pretty complicated to get an accurate print when you have to lay colors over each other. But what if it's just one color? | |
| Jun 13, 2017 at 18:20 | comment | added | Quint | And even a printing press isn't perfect. Systems responsible for printing plates for a press create traps (small adjustments/overlaps where two colors meet) and overprints to hide gaps created by misregistration and the normal stretching of plates over a run. | |
| Jun 13, 2017 at 17:13 | comment | added | melkimx | Thanks! I was wondering what kind of printer allows for accurate alignment, even if it's not something I could ever use or afford. So I think this answers my question. | |
