Embodiment Construction

[0031] see Figure 5 , Figure 5 is a schematic diagram of the ribbon 50 of the first embodiment of the present invention. The ribbon 50 is applied to a thermal printer 20 and can be wound in the ribbon box 28 . The operation mode of the ribbon 50 in the printer 20 is the same as that of the ribbon 30 , so it will not be repeated here. Ribbon 50 is a polymer film on which dyes are placed in a fixed pattern. Figure 5 In the dye area of ​​, Y stands for yellow, M stands for magenta, C stands for cyan, and O stands for transparent protective layer. In addition, T represents a dye-free area, and B represents a shortened unprintable black stripe area. The ribbon 50 is substantially longer than the recurring dye area, protective layer, non-dye area and black stripe area mentioned above.

[0032] Ribbon 50 mounted on image 3 on the printer 20, and program the controller 38 according to the method of the present invention. In addition, the light sensor 34 in the printer 20 wi...

Abstract

A method for recognizing a color of a printing ribbon includes providing a printing ribbon having a repeated sequence of dyed and undyed regions such that output of a photosensor sensing the ribbon is a low or high level based on a threshold. The method includes illuminating a sensing area of the ribbon, moving the ribbon relative to the sensing area, measuring output of the photosensor over time as the ribbon moves, correlating output of the photosensor to the repeated sequence as the ribbon moves to determine the color of the ribbon under the print head, and setting operational parameters of the printer and print head according to the color of the ribbon under the print head. The repeated sequence is unprintable black dye, yellow dye with undyed ribbon, magenta dye, undyed ribbon, cyan dye, and transparent overcoating with undyed ribbon.

Description

technical field [0001] The invention relates to a digital printer, in particular to a printer using a ribbon. Background technique [0002] Digital printers are used in computer systems to print out digital images. One type of digital printer utilizes a print head to heat dyes on a ribbon and transfer them to a print medium. The ribbon includes a plurality of dye areas and a transparent overcoating area, and the dyes on the dye areas can be modulated to approximate true colors in proper proportions. Such printers have been widely used in digital photos at present. [0003] see figure 1 , figure 1 The known thermal printer 20 includes a housing (housing) 22, a thermal print head (thermal print head) 24, a track 26, a movable ribbon cassette (ribbon cassette) 28 and a ribbon (ribbon) 30 , wherein the thermal print head 24 is embedded on the track 26 , and the track 26 is mounted on the casing 22 . The printer 20 also includes a motor (not shown) and a controller (see f...
