DESCRIPTION PRINTING ON SCANNER TYPE DIGITAL INKJET PRINTING MACHINES COMPENSATION FOR STOP DISTANCE ERRORS OF THE PRODUCT TO BE MADE.

Scanner type digital inkjet printers; transversely the product to be printed by scanning, by spraying dyestuff on the product to be printed from inkjet print heads. are the machines that make the bass. Example: inkjet printers used in offices.

These types of inkjet printers are used in offices as well as professionally. It is also used in production. usage area; paper, fabric, tile, wood etc.

In Scanner type digital inkjet printing machines; inkjet print heads By scanning the product to be made transversely, dyestuff is sprayed from the inkjet print heads. the product to be made progresses again and the part to be printed comes under the inkjet print heads, The inkjet printheads scan crosswise again and spray again. This is the transaction By continuing as follows, the printing process is completed on the product to be printed.

Difficulty with Scanner type digital inkjet printers: Inkjet printheads are removed from the inkjet printheads by scanning the product to be printed transversely. After printing with the sprayed dyestuff, the product to be printed will be printed. section advances to come under the print heads and stops when it comes under the print heads.

The shifts at the stop point overlap between the printed part of the pattern and the part to be newly printed. It causes overlaps (FIG.-S) or compression gap (FIGURE-4l). In order to prevent the product movement mechanisms to be printed, the margin of error will be very low. is produced. The nozzle spacings on the inkjet printheads used are usually 0.1 - 0.025. If it is thought to be between mm, the sensitivity of the product to be printed at the moment of stopping will be better understood.

Control of the stopping point of the product to be printed and the stopping position Various methods are used to determine The subject of this patent will be printing. not the stopping point control of the product or the detection of the stopping position, but the detection of stopping errors. It's about compensation.

We have developed; Compensation for errors at the time of stopping of the product to be printed: a- Inkjet print head nozzles of the pattern in the section to be printed shifting. b- Spraying from the end of the previous printing in such a way as to ensure the integrity of the pattern initiation of the transaction.
