Description
DESCRIPTION
DATA TRANSFER AND USE METHOD IN INKJET PRINTHEADS
In inkjet digital printing machines developed for printing patterns to textile or paper, to 5increase the printing spreed, used number of printheads are being increased. For instance, 160 to 240 printheads. For a fast printing, it is required to transfer data to those many printheads simultaneously (synchronously) and fast during printing.
CURRENT METHOD :
Simultaneously (synchronously) and fast data transfer to many printheads is explained as: 10 By processing the image or pattern that will be printed on computer (1), data for each inkjet printhead is created. Those data, is transferred to data distribution unit (2) designed for data transfer system, and stored here FIGURE- 1. Printing is done via transferring those printhead data stored in the data distribution unit (2) to inclined printhead drivers (4)
continuously during printing. Depending on the muchness of the inkjet printheads, data l5distribution unit (2) designed for data transfer system, where the inkjet printhead data is stored can be more than one FIGURE-2.
The hardest difficulty of data transfer during printing is to transfer required data to each printheads at the instant simultaneously. That created simultaneous and fast data transfer difficulty.
0 Inkjet printers used in offices have their own memory unit. Pattern or image data is transferred to those memory units from the computer (1). Inkjet printer performs the printing operation using the data stored in its memory unit. In an advanced professional office inkjet printers, those memory units are mode advanced. However, in such printers, printing is done via transferring the data received from the computer (1), to printheads using the processor 5inside the printer.
DEVELOPED METHOD:
Explanation: Image or pattern that will be printed has certain dimensions. That dimension is referred to as report length. Printing to fabric or paper is done via repeating the image or pattern of one report length continuously.
0 By processing the image or pattern is on computer (1), spraying data required for each printhead is created. Those data is not transferred simultaneously and continuously to printheads during printing. Those data is transferred to memory unit which will be mounted on inkjet printhead driver before the printing. Printing is done via addressing those data
during printing, and transferring the printing data at the inclined address to inkjet printheads (3). Data that is transferred to each printhead driver is specific image or pattern data to the specific driver that is processed on computer. However, printing is done via transferring those different (printhead specific) data to inkjet printheads by addressing those data jointly.
5 Summary of developed system:
• Data won't be transferred to many inkjet printheads (3) simultaneously and
continuously during printing.
• Before starting printing, printing data specific to each printhead (3) will be transferred to ram memory unit placed in inkjet printhead driver (4).
10 · Printing is done via addressing data in inkjet printhead with ram memory unit, and transferring those addressed data to inkjet printheads.
Advantages:
It will bring a solution to the difficulty of transferring data simultaneously and l5continuously to inkjet printheads (3) during printing. Inkjet printing machines will have a simpler structure. It will make designing and producing multiple printhead inkjet printing machines easier. It will make it able to increase number of used in a machine inkjet printheads (3) further. 0FIGURES AND THEIR DESCRIPTION,

DETAILED EXPLANATION
The invention of this paper, is a method to transfer image or pattern related data processed on computer (1) to inkjet printheads (3), and use of those transferred data.
The purpose, is to provide solution to difficulty of sending image or pattern relatedprinting data to inkjet printheads (3) during printing continuously and synchronously. In the designed system, there is no intense printing data transfer to inkjet printheads (3) during printing.
Two different methods are designed for data transfer and use: Method- 1 :
The printing data related to image or pattern processed on the computer (1) are transferred to inkjet printhead driver with ram memory (5), through data transfer channel (line) (8) before printing. The printing data related to image or pattern processed on the
computer (1) are transferred to each inkjet printhead driver with ram memory (5) by separating them according to which data belong to which driver. Instead of transferring data intensely during printing, printing is done via sending data addresses to all inkjet printhead driver with ram memory (5) simultaneously, the data in inkjet printhead driver with rammemories (5) are made transferred to inkjet printhead (3).
Method-2:
The method of processing image or pattern data and transferring and use of them is same as Method- 1. However, to reduce the time loss of switching between image or patterns because of the time needed to transfer data to inkjet printhead driver with ram memory (5), and inkjet printhead driver with ram memory where address (of data) and data input isseparated (6); memory of inkjet printhead driver with ram memory (5), and inkjet printhead driver with ram memory where address (of data) and data input is separated (6) is kept big or another memory is added to the inkjet printhead driver with ram memory (5), and inkjet printhead driver with ram memory where address (of data) and data input is separated (6) - FIGURE-7, FIGURE-8 (Second Ram (14)). It is preferred to make data transfer channel (line)(8) that transfers data to inkjet printhead driver with ram memory (5), or inkjet printhead driver with ram memory where address (of data) and data input is separated (6) and address (of data) transfer channel (line) (9) that is required to make these data usable during printing are separated - FIGURE-6, FIGURE-8. In digital printing machine, while printing image or pattern data in inkjet printhead driver with ram memory (5), or inkjet printhead driver withram memory where address (of data) and data input is separated (6), data image or pattern that will be printed next is made ready by transferring them to other memory unit in inkjet printhead driver with ram memory (5), or inkjet printhead driver with ram memory where address (of data) and data input is separated (6) from the data transfer channel (line) (8). With this approach, switching between image or patterns to be printed is made fast. Inkjet printheaddriver with ram memory (5) can be designed with a DDR, or an SDRAM memory.
