Print production problems are the ones that stop a job rather than stop a machine. The printer runs, the file opens, and what comes off the roll is not sellable – banding across a flat colour, a colour that will not match the proof, white that looks grey, a contour cut that drifts down a long panel. The equipment is rarely broken. Something in the chain between the file and the finished print is out of specification.
That chain has more links than most shops think about day to day: the RIP and its colour management, the profile for the media actually loaded, ink age and storage, the feed mechanism moving media the commanded distance, the heaters or lamps curing it, and the finishing step afterwards. A fault in any one of them produces a symptom that looks like it belongs to another.
The guides collected here work the same way round every time. They explain the mechanism first, because once you know what a subsystem is doing you can usually work out which one is lying to you – and because the next fault will be a different one, and a list of symptoms will not help you then.
They are written for the person standing at the machine with a job due. Each one tries to get you to a decision: whether this is a setting you can change now, a consumable you should have replaced last month, or a service event where continuing to run the machine is going to cost more than stopping it.
If a guide does not settle it, send the make, model and serial, a photograph of the actual output rather than a description of it, and what changed before the problem started. The last of those is the detail that solves most of these.
For sign, wrap, and production print shops, the RIP is the quiet engine behind every job. Onyx, Flexi, and Caldera each turn design files into the color-managed, correctly sized output a wide-format printer actually runs, and when the RIP misbehaves, the symptoms often look like a printer problem even though the cause sits in software. … Read more
White ink is the hardest pigment in DTF printing and the one that fails first when circulation, agitation, and capping aren’t kept in spec. A practical guide to how recirculation works, why it matters, and the daily routine that keeps DTF production running.
Banding on eco-solvent prints is the #1 production complaint in sign and wrap shops, and “run another clean cycle” is the wrong first move more often than it’s the right one. A practical guide to reading the band pattern, isolating the cause, and knowing when the fix is a setting versus a service event.
