DI Proof (1 bit)
Di Proof
DI proof or Data Integral Proof was created in the days when 1 bit tiff workflow is popular. It is a ROOM module that we take CMYK separation in 1 bit format, from any resolution that the RIP generates and down sample to produce a lower resolution contone file. This contone file can be color managed to look the same with its original.
If the original is a higher resolution file, you can create proofs which partially reproduces the dot patterns of the original separations making it possible to check the rosettes pattern on the proof. Compose offers this to go with our 1 bit imposition or plateController product to provide a fast and accurate proofing to customers.
