A kind of colour code type that the utility model provides is located inspection product device automatically, at printed matter the detection colour code is set by adopting, and adopt photoelectric scanning head to scan the method for comparison, overcome the linear array scanning video camera and can't detect overprint error, can't carry out synchronous technical difficulty with encoder when reaching rewinding inspection product.By the chromatography colour code that sets in advance, in printing process, automatically be formed for examining the detection colour code of product mark, a photoelectric scanning head can detect simultaneously, and concentrate and compare, calculate, in time detect defective products, the implementation simple and flexible does not increase additional process, do not increase the operating time, can extensively examine product with the overprint error of various raw material printings.After being completed for printing, forming two ends has the detection and localization synchronous mark, need not again reverse printed matter, directly carries out overprint error and automatically examines product.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation that detects colour code and detection and localization synchronous mark in the utility model.
Fig. 2 is the structural representation that detects colour code and another kind of detection and localization synchronous mark in the utility model.
Fig. 3 is the overall structure schematic diagram of the utility model device.
Among the figure: the first detection and localization synchronous mark 1, detect colour code 2, the second detection and localization synchronous marks 3, photoelectric scanning head 4, computer system 5.
The specific embodiment
In Fig. 1-3, a kind of colour code type is located inspection product device automatically, comprise the computer system 5 for image comparison, the photoelectric scanning head 4 that is connected with computer system 5, be located on the printed matter with detection colour code 2 corresponding to form and aspect with chromatography, described photoelectric scanning head 4 is positioned at the position corresponding with the detection colour code 2 on the printed matter.
Described detection colour code 2 one or both ends are provided with for the detection and localization synchronous mark as comparison basis.The scheme of optimizing is as shown in Fig. 1,2, be provided with for the first detection and localization synchronous mark 1 and the second detection and localization synchronous mark 3 as comparison basis detecting colour code 2 two ends, thus the structure detection side that then need not consider printed matter to.
At least be provided with a shape in described the first detection and localization synchronous mark 1 and the second detection and localization synchronous mark 3 or/and color detects the different color lump of colour codes from other, to obtain the synchronizing datum signal of detection.Concrete wider color lump as shown in Fig. 1,2.
Described detection colour code 2 is corresponding with each printing monochrome ink, and has the distance of setting between the colour code of all kinds.In the scheme of optimizing, distance equates between described detection colour code 2 colour codes of all kinds, so that input signal and the setting value that is pre-stored in the computer system are compared, in order to assess the error of chromatography.
A kind of method that adopts above-mentioned device to detect printed matter may further comprise the steps:
One, on printed matter according to each color ink, the CMYK look of for example commonly using, perhaps the CMYK look adds spot color, and monochromatic detection colour code 2 is set, and is provided for the first detection and localization synchronous mark 1 and the second detection and localization synchronous mark 3 as detection reference at detection colour code 2 two ends; Described detection colour code 2 is corresponding with each printing monochrome ink, and has the distance of setting between the colour code of all kinds.
