Write space between my data & edge of the photomask?
It is important not to go too close to the edge of the mask, since the resist on masks blanks is slightly thicker in the corners and on the edge of the mask blank. We recommend that no features are placed within 10 mm of the edge of the mask.
We would normally add titles out with the exposure (or write) area. The area beyond the exposure area will always be “chrome”.
