MICR Check Stock
Check stock has a significant impact on the resulting quality and security of your MICR
document. Here are a few features that should be considered when selecting a check
stock. Please see Chapter 5: Security Issues for more information on check stock
security features.
Quality
Quality MICR check printing with your Source Technologies’ secure MICR printer
requires check stock that matches the printer’s requirements. Source
Technologies can supply paper specifically made for our printers. If you wish to
order check stock from other suppliers, please show the following requirements
to your sales representative. We will test other suppliers’ paper for a nominal fee.
Layout
Layout your check design before any paper is purchased or layout your design to
existing check stock. Keep perforations, orientation, special logos and any color
elements in mind. The printer can print just about anything as long as it is black.
Weight
We recommend 24 lb. - 29 lb. paper.
Stiffness
We recommend Taber M.D. 2.5 and C.D. 1.1 minimum.
Smoothness
For best toner fusing, we recommend rougher surfaces within the base printers’
specifications, and the Paper Specifications for Checks, X9.100.10. We
recommend a smoothness range of 150 to 200, Sheffield.
Paper Grain Direction
When using 24 lb. - 29 lb. bond paper we generally support either long or short
paper grain. Overall performance in the bank’s reader/sorters is best when the
resultant grain direction is left to right when viewing the check.
Perforations
All perforations in the stock should be Laser-Cut or Micro-Perfs (20 or more cuts
per inch). Larger perforations can produce excessive paper chaff and result in
damage to the toner cartridge. Perforations should be ironed by the paper
supplier to reduce nesting and potential double feeding.
Moisture
The paper moisture content should be between 4.7 and 5.5%. Storage conditions
have much to do with the final moisture content of most papers. Store your check
stock in a cool, dry, environmentally stable and secure area. Protective
wrappings should be removed just prior to use.
