MICR Check Stock
Check stock has a large 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 4 for more information on check stock security features.
Quality
Quality MICR check printing with your ST 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 in mind, perforations, orientation, special logos and any
color elements. 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 X9.18. 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 banks 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 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.
