AUTO CRACK

AUTO CRACK

This system consists of two different pastes which are Auto Crack White and Auto Crack Clear.

Auto Crack White is a high opaque white and Auto Crack Clear is Clear base , which both of them form a super hard dry film with low coalescing properties when dry. These are ready for use water base cracking ink that can be screen printed immediate out of its can.

Auto Crack White is an excellent product for use on dark fabrics where maximum opacity with cracking finish is required, where else Auto Crack Clear is a highly translucent base that can be used in conjunction with a wide range of waterbased pigment concentrated to achieve desire colors of the crack print.

• PROCESS
  Underbase should be touch dry prior laying down the cracking paste. First Print 1 Time Auto Crack basecoat that should be touch dry prior laying down the cracking paste. then print Auto Crack White / Clear mixed Colour 2 Times with 3 Strock. Natural Dry the fabric, you can see the Crack immediately, don't remove the fabric from table/ pallet before complete cracking, as Cracking will not happen once removed from pallet.
• MESH
  43S/110S - 49S/120S mono-filament at 20 Newton for high opacity. 39T/100T-51T/130T mono-filament at 20 Newton for cracking paste with emulsion thickness of 200µm. 100 Nylon Mesh.
• SQUEEGEES
  For maximum opacity 50/60 durometer hardness squeegees are recommended for underbase. To achieve an excellent cracking effect use 45/55 durometer hardness squeegees. Soft tables are most and multiple squeegee strokes are recommended to improve on cracking ink deposit.
• DRYING
  All underbase should be touch dry prior laying down the cracking paste. To achieve even cracking, all intermediate cracking color is to be cool air dry at temperature below 50°C/122°F. Final drying and cracking are suggested at 150°C/302°F for 3 minutes with Airflow recommended are 2500 cfm/70.79cmm for proper polymerization.
