- Why Print Shops Are Losing Margin in Finishing, Not Production
By Kjell Karlsson | Updated July 2026 | 12-minute read The conversation about print shop profitability almost always ends up at the printer. Ink cost per millilitre. Material cost per square metre. Equipment amortisation. These are real numbers that matter, and shops that do not know them are running in the dark. But fixating on… Read more: Why Print Shops Are Losing Margin in Finishing, Not Production - Building a Print Shop Workflow That Scales: Where Consistency Comes FromBy Kjell Karlsson | Updated July 2026 | 13-minute read Print shops that struggle to scale are rarely struggling because they lack capacity. They are struggling because the work that gets done depends too heavily on who is doing it. The experienced operator produces consistent output. The new hire produces variable output. The owner steps… Read more: Building a Print Shop Workflow That Scales: Where Consistency Comes From

- 10 Questions to Ask Before Buying a DTF PrinterBy Kjell Karlsson | Updated July 2026 | 14-minute read Most DTF printer purchases are made on the wrong information. The buying decision gets driven by sticker price, a YouTube review from someone running the machine at one-tenth of production volume, or a spec sheet that tells you what the printer can do under ideal… Read more: 10 Questions to Ask Before Buying a DTF Printer
- Wide Format Market Landscape 2026Market Landscape · 2026 Wide Format 2026: Consolidation, Chemistry, and the Software Layer Five research firms value this market at five different numbers. Three OEMs changed hands in eighteen months. One regulation lands on August 12. Here is what actually moves margin on your floor — and what is just a press release. Hardware OEMs… Read more: Wide Format Market Landscape 2026
- How to Price DTF Transfers: A Framework for Print Shops and Transfer SuppliersBy Kjell Karlsson | Updated June 2026 | 12-minute read Most DTF shops that struggle to make margin aren’t losing it on materials. They’re losing it on the gap between what they think a transfer costs to produce and what it actually costs. The number used for pricing is typically based on ink cost alone,… Read more: How to Price DTF Transfers: A Framework for Print Shops and Transfer Suppliers
- The Real Cost of DTF Printing: A Breakdown for Shop OwnersBy Kjell Karlsson | Updated June 2026 | 13-minute read Ask most DTF shop owners what it costs to produce a transfer and they will give you an ink cost.

Almost none will include equipment depreciation, labour, or the overhead cost that sits behind every hour… Read more: The Real Cost of DTF Printing: A Breakdown for Shop Owners
- Colour Accuracy in Wide Format Printing: Why It Fails and How to Fix ItBy Kjell Karlsson | Updated June 2026 | 11-minute read Colour accuracy in wide format printing fails at predictable points in a predictable sequence.

Most colour complaints that arrive… Read more: Colour Accuracy in Wide Format Printing: Why It Fails and How to Fix It
- Flatbed vs Roll-to-Roll UV Printers: Which Configuration Fits Your Application MixBy Kjell Karlsson | Updated June 2026 | 12-minute read Flatbed and roll-to-roll are two fundamentally different mechanical configurations for UV inkjet printing, and the decision between them is not primarily about print quality — both produce comparable output from equivalent hardware. It is about application fit. A flatbed prints rigid substrates up to a… Read more: Flatbed vs Roll-to-Roll UV Printers: Which Configuration Fits Your Application Mix
- What Is a RIP in Printing? How Raster Image Processors Work in Wide Format WorkflowsBy Kjell Karlsson | Updated June 2026 | 10-minute read A RIP — Raster Image Processor — is the software layer that sits between your design file and your printer. It translates artwork into printer-native instructions: which nozzle fires, at what moment, with what ink volume, at what position on the substrate. Without it, a… Read more: What Is a RIP in Printing? How Raster Image Processors Work in Wide Format Workflows
- Gang Sheet Printing Explained: Yield Math, File Prep, and Cost ImplicationsBy Kjell Karlsson | Updated June 2026 | 10-minute read A gang sheet is a single print substrate that carries multiple designs arranged to fill the available print area as efficiently as possible. In DTF production, it is the primary method for reducing per-print cost and increasing throughput. Shops that do not use gang sheets… Read more: Gang Sheet Printing Explained: Yield Math, File Prep, and Cost Implications
- Hot Peel vs Cold Peel DTF Transfers: What the Difference Actually Means for ProductionBy Kjell Karlsson | Updated June 2026 | 10-minute read Hot peel and cold peel are not quality levels — they are production specifications determined by the adhesive powder formulation used on the transfer. The difference in surface finish, throughput speed, and failure modes between them is significant enough that understanding which you are running,… Read more: Hot Peel vs Cold Peel DTF Transfers: What the Difference Actually Means for Production
- Humidity and Temperature Control in DTF Production: The Numbers That MatterBy Kjell Karlsson | Updated June 2026 | 11-minute read Most DTF troubleshooting guides treat humidity and temperature as background context — something to mention briefly before getting to the real causes. This guide treats them as primary production variables, because that is what they are. Environmental conditions affect every stage of the DTF production… Read more: Humidity and Temperature Control in DTF Production: The Numbers That Matter
- DTF Powder Not Sticking: 7 Root Causes and How to Fix ThemBy Kjell Karlsson | Updated June 2026 | 13-minute read DTF powder adhesion failure is one of the most frustrating production problems to diagnose because the same symptom — powder not bonding to the transfer, or transfers not adhering to fabric — can trace back to seven different root causes. Most troubleshooting attempts fail because… Read more: DTF Powder Not Sticking: 7 Root Causes and How to Fix Them
- White Ink Clogging in DTF Printers: Causes, Prevention, and RecoveryBy Kjell Karlsson | Updated June 2026 | 12-minute read White ink clogging is the most common production problem in DTF and the most preventable. It is also the problem shops most consistently misdiagnose — chasing the symptom (missing nozzles, inconsistent white coverage, failed transfers) without addressing the root cause. This guide covers what is… Read more: White Ink Clogging in DTF Printers: Causes, Prevention, and Recovery
- Eco-Solvent vs Latex vs UV Ink: How Wide Format Shops ChooseBy Kjell Karlsson | Updated June 2026 | 11-minute read Most shops do not choose their ink technology — they inherit it with the printer they bought, or they default to whatever the dealer recommended. That works until the application mix changes and the equipment stops fitting the work. This article is for shops making… Read more: Eco-Solvent vs Latex vs UV Ink: How Wide Format Shops Choose
- DTF vs DTG Printing: What Shop Owners Actually Need to KnowBy Kjell Karlsson | Updated June 2026 | 10-minute read This comparison gets asked constantly, and most answers online get it wrong because they frame it as a quality debate. It is not. DTF and DTG are different production tools with different operational trade-offs. The right choice depends on your fabric mix, your order profile,… Read more: DTF vs DTG Printing: What Shop Owners Actually Need to Know
- What Is Large Format Printing? Applications, Technologies, and Industry StandardsBy Kjell Karlsson | Updated May 2026 | 9-minute read Most people in the trade use “large format” and “wide format” interchangeably and mean roughly the same thing. But the technology underneath that label covers four distinct ink chemistries, dozens of substrate categories, and output widths from 18 inches to 5 metres and beyond. This… Read more: What Is Large Format Printing? Applications, Technologies, and Industry Standards
- What Is DTF Printing? A Technical Overview for Print ProfessionalsBy Kjell Karlsson | Updated May 2026 | 8-minute read DTF printing is one of the fastest-adopted transfer technologies in garment decoration — and one of the most consistently misunderstood at the production level.
