Discussion on Flexographic Printing Experience

One issue that is often mentioned when training in flexographic printing companies is ink management. If the ink management is in place, the efficiency of the printing press will be improved to a certain extent, and the loss will also be reduced. The frequently mentioned problems are as follows (only a part of them are listed here): the entire printing workshop realizes the standardization of cell volume; the standardization of the ink supply system (squeegee blades on all printing machines); the ink preparation procedure; the inventory control between the inks; Relevance to printing presses. In this practical article we will discuss the relationship between the proofer and printing.

Test procedure for the correlation between manual proofing machine and printing machine:

1. Before starting the operation, confirm and mark the three test inks to ensure that the PH value and viscosity of the ink are normal. Choose a light shade of red, blue and green 2. Collect three to four commonly used printing materials for testing;
3. Commission the printing machine and select the anilox roller used for spot color printing;
4. Install a gradation plate on one plate cylinder, and install a solid negative plate on the other cylinder;
5. Use a gradation plate and a negative plate to print the field with test ink on each substrate. If the sleeve has not been used in production, there may be a jump in the tone. The hardness of the sleeve and the printing plate material are different, and the amount of ink transferred may have different deviations. Therefore, the test and comparison of the two are very important.
6. Record the technical data of the anilox roller (the mesh volume bcm and the number of anilox lines and the anilox roller label), and label the printed sample. Bring the proof sheet and test ink back to the ink room. Use a simple form to determine the appropriate anilox roller;
7. Select the anilox roller of the manual proofing machine that is closest to the cell volume of the anilox roller used on the printing machine and install it on the manual proofing machine;
8. Use the manual proofing machine for proofing and compare with the printing machine's proofs; repeat the above process until the proofing proofs and the printed proofs match to determine the matching proofing anilox roller;
9. Confirm the proofs with the data measured by naked eyes or spectrophotometer;
10. Use other test inks for proofing to confirm the test results;
11. Record the test results in the corresponding anilox roll table;

Reasonable use of manual proofing machine to maintain accurate records, through this simple link to reduce the time of color calibration, reduce waste, and improve the efficiency of printing presses. If you need more help, please contact the ink and anilox supplier. Respond easily and keep relevant records at any time.

Tools that need to be configured in the ink room

Efficient ink room management must ensure that at least the following instruments and equipment are equipped:
1. The high-quality manual proofing machine with squeegee ensures the stability of ink measurement;
2. Micro balance for measuring and making test samples, suitable for weighing batches of ink;
3. The latest version of Pantone Manual;
4. Sample stand for detecting color samples;
5. Acidity meter (PH value measurement) and Zahn cup to ensure stable ink performance;
6. Spectrophotometer;

In this article series, Mr. Vincent DiTrolio, President of the DiTrolio Flexographic Printing Association, will explain the common practical problems in flexographic printing. Mr. Vincent DiTrolio has 19 years of experience in the flexo printing industry and has been providing training and consulting services to the industry through the DiTrolio Flexographic Printing Association he founded, which is jointly approved by the Illinois State Department of Education and the U.S. Department of Veterans Affairs established.

Is the press operator Joe still using the $ 300,000 press as a color proofer? Does Joe still think he performs color calibration on the press faster than in the ink room? Indeed, Joe can perform on-site color correction by increasing or decreasing the amount of ink, and finally get a satisfactory proof. But the downside is that there will be some problems next. Joe had to try again the next time he printed. When he remembered whether it was added or decreased, the printer would have to stop and wait. Now we think that Joe is a great operator, he can use the conditions he has to produce high-quality products, but in order to further improve his ability to remain competitive in the global economic environment, we need to provide suitable instruments , Operating procedures and practical capabilities to improve operating efficiency and production capacity.
