When Off-the-Shelf Doesn’t Fit
Catalog stock works for most jobs. The hard ones — tight gauge tolerances, unusual sheet sizes, qualified print-grade finishes, multi-substrate sourcing, private-label runs — are why K&R has lasted 35 years. Send us your spec. We’ll come back with a substrate that works.
What we engineer
Gauge matching
Non-standard gauges sourced or converted from stock material.
Finish matching
Gloss, matte, satin, textured, anti-glare, anti-static.
Print-grade qualification
Substrates qualified against your specific press: HP Indigo, EFI, Roland, Mimaki, Vutek, screen lines, offset/litho presses.
Multi-substrate sourcing
Single-PO consolidation across PVC, HIPS, PC, PETG, polyester, PE, PP.
Custom sheet sizes
Slit, sheeted, and cut-to-size to your dimensions.
Private-label runs
Branded packaging, bulk runs, consigned inventory programs.
Process
- STEP 1
Spec intake
Send drawings, sample, or written spec. We'll confirm what's possible.
- STEP 2
Sample qualification
Sample shipped, you run it through your process, we adjust based on results.
- STEP 3
Validation
Final spec locked, datasheet and CofC issued.
- STEP 4
Production
Stocked, slit, sheeted, and shipped on your schedule.
