Answer Wiki. While Printing, the term Collate for printers refers to the gathering and arranging of individual sheets or other printed components into a pre-determined sequence. Basically, Collating creates consistent, logical sets from multiple parts in printers. Collated can also be termed as collected and combined (texts, information, or sets of figures) in proper order in printers. A short-run perfect bound book would require its pages to be collated in numerical order before it could be bound. The printer collate works the same way while printing, It is Also, multi-part forms and checks are created from individual sheets collated in a specific sequence. Uncollated, would be the opposite, meaning something that wasnât collected and arranged into any particular order when we print.
