Abstract
The utility model provides an envelope color tint tester detecting the background color reflectivity and the red frame optical parameters of envelopes. The utility model is characterized in that red light is incident upon the tested surface by means of six-furcation in a 45 DEG mode. The division light in the vertical direction receives two optical signals in the specific wavelength range in a small region. The division light is processed by means of a computer, and the background color reflectivity and the red frame optical parameters of the envelopes are displayed. The problem of testing accuracy in the small area is consequently solved. The utility model has the advantages of simple structure, convenient use and maintenance and is an indispensable device which tests and identifies if the content of the positive surface of the envelope conforms to national standard.
Description
The utility model relates to a kind of equipment that detects envelope colourity reflectivity and red frame parameter.
The reflectivity of regulation kraft and paper for covering books all should not be lower than 38% among State Standard of the People's Republic of China's " envelope "; Receiver's postcode sash color in the positive upper left corner of envelope should be golden red; Contrast to background color under green glow should be greater than 58%, and the contrast to background color under ruddiness should be less than 32%, and color and luster is even, and must not break.
Reflectivity is meant when ripple reaches the interface of another kind of medium by a kind of medium in communication process, return the phenomenon of former medium, light reflectivity on M.G. pure sulphite paper is meant kraft and paper for covering books, paper is measured under wavelength 480-570mm wavelength with the optics colorimetric detection instrument that is not less than fine grade; The optics colorimetric detection instrument that red frame color also should be not less than fine grade detects under 480-570mm and 600-680mm wavelength, and above-mentioned is to stipulate in the standard.Envelope background color reflectivity is low excessively, is unfavorable for that letter manages letter and letter sorting automatically, and spray printing is gone out the bar code identification tape comes difficulty.
So-called contrast (PCS value) refers to the difference of a kind of object and another kind of object reflectance, the ruddiness of stipulating in envelope standard contrast range down and under the green glow, it is a comprehensive whether golden red of red frame color of accurately estimating, the PCS value equals envelope background color reflectivity and deducts under green glow or the red light wavelength behind the red frame reflectivity again divided by envelope background color reflectivity, in other words, whether estimate red frame color correct, red frame reflectivity is little under green glow, and red frame reflectivity is big under ruddiness, then thinks the sash of the Standard Colors of golden red;
In the standard also regulation frame linear dimension be 0.7 ± 0.2mm.
But whiteness is taken into account spectrophotometer both at home and abroad at present, only with the reflectivity of doing the object background color, and the frame line and the contrast of red frame on the envelope can't accurately be reflected; It is 1mm that other whiteness is taken into account spectrophotometer detection minimum area diameter, and can't finish red frame 0.5mm diameter small size test, therefore, needs the envelope colorimetric detection instrument that detects the envelope of surface content on the market.
The purpose of this utility model provides a kind of envelope of surface content that detects, and especially accurately detects the envelope colorimetric detection instrument of envelope background color reflectivity and red frame parameter.
The utility model is to realize like this.
The utility model light harvesting is learned, machinery, the new exclusive envelope colorimetric detection instrument of advanced technologies such as microprocessor, optical measuring system is by light source, light conductor, object lens, spectroscope, one road ruddiness mechanism, one road green glow mechanism, optical device such as eyepiece constitute, liftable and work top that can parallel adjusting can be put measured object, when light source irradiation behind light conductor, light conductor is divided into 6 support bodies again and is incident in the sample surface for 45 °, also pass through the ruddiness collection of 480-570nm green glow and 600-680nm respectively through the spectroscope colour filter by optical system 0 ° of vertical direction, through opto-electronic conversion, microprocessor processes shows the red frame parameter value of tested envelope on display screen.
The utility model advantage is:
1. by the ruddiness green glow small size zone reflects light degree is tested, can accurately reflect red circle lattice color colorimetric parameter and red frame printing quality, if have the uneven blank spot of color and luster also can detect in the red frame, provide advantage for postcode in the red frame of machine recognition like this.
2. adopt 45 ° of incident structures of soft optical conductor 6 branches, light intensity improves 6 times, thereby has solved small size test incident intensity problem.
3. the utility model is simple in structure, easy to operate, is convenient to maintenance, changes components and parts.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model structural representation.
