That old printer tech's advice about cyan was backwards for my shop
Back in 2017, this guy named Roy who'd been running a press in Chicago for 30 years told me to always bump cyan up 5% before any batch run. I trusted him because he'd seen everything. Last month I finally tracked down why my navy tees kept coming out purple-ish after 3 straight orders. Turns out my RIP software had a default that already boosted cyan, so Roy's rule was double-dipping. I ran a test with his settings off and the greens finally looked right on the sample I showed a client in Denver. Anyone else get stuck following old habits that don't match newer machines?
My buddy Stan had the same thing happen back in 2012 but with a paper cutter, this old timer told him to always add a quarter inch to the trim on card stock... turns out the newer guillotine was already auto-adjusting for creep and he was losing half his margin on every job. He finally figured it out after a client in Austin complained their business cards looked smaller than the proof... spent three days recalibrating the whole shop over an old habit. Sometimes the old tricks just don't translate, you know?
