Many quality disputes in printing or embossing are not actually caused by explosions on the production line, but by foreshadowing during sampling: uneven solid substrate, unstable transfer, fluctuating layer thickness, unclear color, and falling off the screen as soon as the speed is raised... Once these hidden dangers are carried on the machine, they will be consumed in rolls.

Instead of putting out a fire, it's better to move the 'bulk problem' to the sampling station. And this is precisely the value of RK in the UK: condensing the four most unstable variables of "ink x plate roller/mesh roller x substrate x process" onto a controllable and reproducible small platform, and clarifying the stable range during the sample stage.

It can be said that when you treat the sample as an "executable instruction" rather than a "good-looking image", mass production will naturally stabilize.

First, turn complex variables into visible 'windows'. KPP gravure printing in RK, UKInk sampling machineOn the FLX100 flexographic ink sampling machine, perform a small-scale scan of key parameters such as line count/volume, pressure, speed, and drying, and you will quickly find the stable and efficient "effective area" instead of continuing to rely on vague experience for trial and error.

After finding the effective area for investigation, the sample is not just a "beautiful picture", but a practical production line instruction: bind the sample with the parameter card, and whoever accepts the order will follow the same "ruler". At the same time, transform communication from experiential feelings to data - record necessary indicators such as color, layer thickness, clarity, etc. at the moment of sampling; The next step is to review the color difference and wear resistance, and change "looks good" to "speaks clearly".

Faced with the demand for large-area solid substrates, metalized films, or high coverage power, RK's KPP (K Printing Proofer) in the UKgravure inkThe sampling machine is the machine that "fills the screen and pulls up the layer thickness".

The electronic engraving plate used in KPP gravure ink sampling machine, coupled with variable speed drive, can quickly produce gravure printing/Flexographic inkHigh quality samples; The sampling speed can reach up to 40 meters per minute, which is sufficient to operate the "high line count, thick transfer" working condition on desktop level equipment. Sample making is not about posing, KPP is about showing you the "side laid out according to the intaglio logic": thick, dense, uniform, and replicable.

More importantly, the KPP gravure ink sampling machine is naturally suitable for judging the linkage between formula and image. When you fine tune the mesh hole and scraper, or change the solvent ratio, you can immediately see the difference in coverage, layer thickness, and leveling on the sample; The cleaning and maintenance are also very clean and efficient, and the solvent resistant components eliminate the entanglement of switching formulas back and forth. These features make KPP the "same ruler" for research and development, computer color matching, quality control, and customer display.

On the other hand, the FLX100 Flexiproof 100/UV ink proofing machine is more like a small machine that maximizes the quality of flexographic printing: clean edges, sharp lines, and fast process evaluation.

It can use water-based, solvent based, or UV flexographic ink to make samples on various substrates such as paper, board, film, foil, etc; The speed range is large, reaching about 100m/min, which means you can use the "speed close to the machine" to verify the ink transfer and drying rhythm, without the embarrassment of being unable to control the speed as soon as it is increased.

Even better, the FLX100 flexographic ink proofing machine adopts the process design of production thinking - selecting the mesh roller, setting the speed, curing, and changing the material, step by step, to solidly achieve "clarity and printing stability"; The testing method is also aligned with practical standards such as ISO 2834-2, and the data produced can match the industry discourse system.

Many people see the FLX100 as a mirror for flexographic printing: when you switch to a higher mesh roller, lower the embossing to "kiss impression", or increase the speed by half, the sample will immediately tell you whether the balance between clarity and coverage has been reached. And this happens to be the most difficult and decisive step for success or failure in the soft version.

The 'second eye' after sampling

Rapid assessment of color difference and wear resistance

The sample is over the eye, but we still need to go through the data. Color difference and gloss will tell you the bottom line of visual consistency, while Naimo will tell you the tolerance of transportation and stacking.

In the next issue, Zhanlin Instrument will use Konica Minolta CM-26DG portable spectrophotometer and Sutherland 2000 friction tester to perform a "color+wear resistance" closed-loop test, turning "visible beauty" into "clear qualification".

(First spoiler: Sutherland's method is one of the commonly used wear-resistant evaluation paths in the industry, such as ASTM D5264, which observes scratches and barcode readability under constant load and reciprocating times.). ）

Take the sample as an instruction

Instead of 'posters'

The significance of sampling is not to "prove that it used to look good", but to give the production line an executable instruction. When KPP stabilizes the "thick and full" and FLX100 connects the "clear and sharp", what you bring to the production line is no longer a lucky sample, but a set of reusable windows and rhythms.

If you are hesitating about how to choose between concave and soft, or how to match the number and speed of the mesh roller, why not come and talk to us. Zhanlin Instrument can combine your ink, substrate, and image targets to arrange RK sampling demonstrations and parameter discussions - eliminating bulk issues on the sample table.
