AI Technical Summary

Problems solved by technology

In addition, by-products can contaminate laser optics or surfaces that come into contact with reaction products
For example, when a transparent cover is used to obtain a hypoxic environment, the transparent cover may become dirty due to by-products, thereby also reducing the effectiveness of the laser beam passing through said transparent cover

Embodiment Construction

[0037] figure 1 The printing device 1 shown in is an inkless printing device 1 in which a paper object 2 is printed by carbonization of said paper object 2 . However, it is worth noting that despite the figure 1 The paper object 2 is shown in the form of paper 2 , but the paper object 2 may comprise paper 2 in any form or shape, including cardboard 2 and cardboard box 2 among others. Note also that the invention is not limited to the paper substrate 2 described in the examples, but may also include the printing of other materials that develop contrast when heat or light is shone on and / or below the surface Variety. This contrast change enables readable printing on the material. Suitable materials include, inter alia: paper, cardboard, cellulose-based materials such as wood and cotton, textiles, glass, metal, plastics and mixtures of the above with other materials in amounts sufficient that their treatment results in a sufficient contrast change to achieve carbonization.

Abstract

The present invention relates to a printing apparatus. The printing apparatus comprises a feed, a printer, a controller configured to control operation of the printer, and a print quality sensor configured to acquire print quality information, wherein the controller is configured to adapt operation of said printer based on the print quality information. The invention further relates to a printingmethod. The method comprises the steps of: printing on a substrate in a printing operation; acquiring print quality information; and adapting the printing operation based on the print quality information.

Description

technical field [0001] The present invention relates to a printing device with improved print quality control. Print quality is interpreted as the print quality on the printed object. Background technique [0002] Conventional printing devices use ink in various ways to print images on a substrate such as paper. Commercially available printing devices include toner-based printing devices, liquid inkjet printing devices, solid ink printing devices, and dye sublimation printing devices. The use of ink has several disadvantages, one of which is the limited capacity of the ink cartridges. Another disadvantage is that liquid ink may dry out and clog the nozzles of the printing device, for example when the printing device is not used for a long period of time. [0003] Attempts have been made to provide inkless printing devices, and prior art inkless printing devices include thermal printing devices which work by selectively heating areas of special thermal paper. Monochrome t...
