As a flexo printer, there are several must-have tools you need to have on hand to secure, control, and manage data throughout the run, ensuring the accuracy and consistency you desire.
Some of the tools we recommend a must have are:
· THREAD COUNT MAGNIFIER: with this, you can inspect the print quality and determine the resolution or definition of the printed image. Through the magnifying glass you can see the smallest details and count the number of threads or lines per inch that have been used to create the image. The number of threads directly affects the resolution of the image and the quality of the print. With the magnifying glass you can verify that they do not present defects that could affect the appearance or legibility.
· DENSITOMETER SPECTRUM: with it, you can measure the amount of ink that is deposited on the surface of the material and make sure that the ink is being applied evenly. You’ll be able to measure the density of different color tones and verify that colors are at the correct values based on job color specifications, ensuring accurate and consistent color matching. In addition, you can use it to make adjustments to the press for machine speed, plate pressure, and ink adjustment, ensuring that ink transfer occurs optimally.
· TAPE MEASURE: You can measure the length and width of the printing band, check the alignment and fit of the printing plate, and color registration (exact match) with the final design. You can also use it to measure the diameter of the printing roll and anilox roll, making sure they are set to the required specifications.
· BLADE or EXACT: used to cut and trim printing materials. We recommend that you have different types of blades, (straight, curved, serrated, etc.), to adapt to different jobs.
· ZAHN CUP: with this tool you can measure the viscosity of inks and other low-viscosity liquids. If the viscosity is too low, the ink will spread too far on the substrate and may cause registration and print quality problems. If the viscosity is too high, the ink may not transfer properly and result in insufficient coverage. This allows you to quickly and accurately measure viscosity, helping you detect and correct problems before they occur.
· STOPWATCH: used in conjunction with the Zahn Cup to measure the flow time of the ink through the orifice of the cup and thus determine the viscosity of the ink. Once the ink flow time has been measured, a specific conversion table is used to convert this time into a measure of viscosity.
· PH METER: Having it on hand will allow you to easily measure the acidity or alkalinity level of inks before each run, to later compare the measurement results with the pH values recommended for the specific ink to be used. You should be aware that if the pH is too low or too high, the ink may not adhere properly to the substrate, causing registration problems, smearing, or even ink separation.
As you can see, and although they seem simple, each tool has a specific use with a common goal. Having them on hand means consistent print runs and time optimization.
If you have doubts about what or which of them adapts to your printing process, write to us, we will be pleased to advise you.
