Description

To the discrimination method of writing with the civilian juxtaposition sequencing of seal
Technical field:
The present invention relates to a kind of writing, print the method that civilian feature is differentiated file.
Background technology:
To the check of writing with the civilian juxtaposition sequencing of seal, the difficult point of juridical authorities in literary composition inspection work often, its main cause: the one, with the naked eye be difficult for differentiating, must be by means of the instruments of inspection of necessity, and the instruments of inspection is generally expensive, and juridical authorities of basic unit difficulty has complete outfit; The 2nd, the diversity of writing implement, as burnt black ink, blue-black ink, ballpoint pen oil, transfer paper manifolding form etc., situation is complicated; The 3rd, seal impression and writing time are different in size to be caused, and the feature that causes being reacted is not quite similar.Still there are not a kind of convenience, juridical authorities of accurate, low for equipment requirements, suitable basic unit method of operating in the present judicial inspection.
Summary of the invention:
The object of the present invention is to provide a kind of convenience, accurate, low for equipment requirements, be particularly suitable for juridical authorities of basic unit method of operating.
Technical solution of the present invention is:
A kind of to the discrimination method of writing with the civilian juxtaposition sequencing of seal, its feature: comprise the following steps:
1. the sample that will differentiate is taken a picture at microscopically, forms photomicrograph;
2. according to writing and the different modes that the civilian juxtaposition of seal forms, set up test sample, and test sample is taken a picture at microscopically, form the contrast photomicrograph;
3. the contrast photomicrograph that 2. obtains of photomicrograph that 1. step is obtained and step carries out the feature contrast, find out the photomicrograph of the test sample identical, thereby draw the writing and the civilian juxtaposition sequencing of seal of sample with the photomicrograph feature of sample formation.
Described microscope is an ordinary optical microscope.The step step of taking pictures 1. is: an ordinary camera is fixed on the tripod, after the optical microscope energized, open the base side light lamp, sample is placed on the microscopical observation place, observe focusing, after treating that feature is clear, observe camera lens for one with the camera lens aligming microscope, the camera height can be to till last with the microscope camera lens, and near the microscope camera lens, then camera is focused, till the feature of in camera lens, clearly seeing sample in the microlens or test sample, then, the whole corral in the contact site of camera lens and microscope camera lens is lived, open camera and take pictures with about one 15 centimeters double-deck black cloths.
The present invention is convenient, accurate, low for equipment requirements, is to be particularly suitable for juridical authorities of basic unit method of operating.
The invention will be further described below in conjunction with embodiment.
Embodiment:
1. the sample that will differentiate is taken a picture at XLT-3400 type microscopically, forms photomicrograph: an ordinary camera is fixed on the tripod.After optical microscope (XTL-3400 type) energized, open the base side light lamp, sample is placed on the microscopical observation place, observe focusing, after treating that feature is clear, observe camera lens with one of the camera lens aligming microscope, the camera height can be to till last with the microscope camera lens, and near the microscope camera lens.Then camera is focused, till the feature of in camera lens, clearly seeing sample in the microlens or test sample.Then, the whole corral in the contact site of camera lens and microscope camera lens is lived, be subjected to the intrusion of extraneous light when preventing camera exposure and influence the quality of photo, open camera and take pictures with about one 15 centimeters double-deck black cloths.
2. according to different writing ink (comprising burnt black ink, blue-black ink, ballpoint pen oil, transfer paper manifolding form), writing length (writing after promptly writing, print civilian drying after impressing) with the civilian juxtaposition sequencing (write afterwards earlier and impress, impress earlier and afterwards write) of seal, writing time, set up test sample, and with test sample microscopically set by step 1. same procedure take a picture, form the contrast photomicrograph;
3. the contrast photomicrograph that 2. obtains of photomicrograph that 1. step is obtained and step carries out the feature contrast, find out the identical test sample of photomicrograph feature--the photomicrograph of-" blue-black ink; impress earlier and afterwards write " that forms with sample, thereby the writing that draws sample with the civilian juxtaposition sequencing of seal is: impress earlier and afterwards write.
The test sample photomicrograph that 2. above-mentioned steps is set up has following feature:
(1) burnt black ink writing and the feature of printing civilian sequencing
Burnt black ink mainly contains carbon black and water is made, and is absorbed very soon after writing on the paper, and burnt black ink is fugitive color not, does not have transparency.And ink paste seal stationery has transparency, can not the overall absorption burnt black ink after impressing on the paper.
1, writes the feature of afterwards impressing earlier.The first, see through red ink paste seal literary composition and can see the blackness handwriting lines.The second, the writing lines are more complete, do not take off disconnectedly, do not produce ANOMALOUS VARIATIONS.The 3rd, at writing lines and the civilian overlapping of seal, on black lines, be covered with one deck red ink paste, the writing lines that do not cover the seal literary composition with the next door have significant difference.
2, impress earlier the back writing feature
Because the drying time of red ink paste seal literary composition is longer than the time of burnt black ink drying, and ink paste seal literary composition can not absorb burnt black ink on the whole fully, so, write immediately after impressing with print civilian drying after write on feature, reflect different.
1. promptly write feature after impressing: the first, because red ink paste Yin Wenshang is not dry, burnt black ink writing lines fracture or water droplet shape occur at the civilian juxtaposition of seal place.The second, the burnt black ink color does not change.
2. print the dry back of literary composition writing feature: the first, the stroke lines contraction can occur at the civilian overlapping of seal and attenuate, but the writing lines are in the ordinary course of things, fracture can not occur.The second, the color of ink can not change.The 3rd, the blackness handwriting lines reflect clearly on the seal literary composition.
(2) Blue-Black Ink Writing and the feature of printing civilian sequencing
Blue-black ink belongs to dye ink, and water cut is more, generally speaking, writes on paper, and its ink is very fast to be absorbed by paper.Blue-black ink can absorb ink paste seal literary composition, and ink paste seal literary composition can not absorb blue-black ink on the whole fully.Blue-black ink with the naked eye at first view, is thought blue-black ink by mistake black ink sometimes because the composition of blueness, black dyes is arranged.After amplifying, just be easy to tell black ink or blue-black ink with the optics microphotograph.Because after amplifying, blue composition just clearly.Sequencing to blue-black ink and ink paste seal literary composition is analyzed, and its feature is as follows:
1, write the feature of afterwards impressing earlier: the first, it is more complete to see through red discovery writing lines, does not occur taking off disconnected or rare.The second, at writing and the civilian juxtaposition of seal place, variation has taken place in the color of writing lines, is varied to black by original blue-black.The 3rd, the writing lines are fuzzy.
2, the back writing feature of impressing earlier: the first, the writing lines occur taking off disconnected or rare.The second, the color of lines changes, is transformed into black by original blue-black.The 3rd, the reflection on the seal literary composition of writing lines is more clear.Above-mentioned feature can appear equally dry back the writing also with blue-black ink of seal literary composition.
No matter the sequencing that Blue-Black Ink Writing and seal literary composition form is writing preceding or writing after, its color all can be varied to black by original blue-black, distinguish successively, mainly be whether to change with the sharpness of lines from the writing lines to differentiate.
(3) black gel ink pen writing and the feature of printing civilian sequencing
Gel ink pen is present popular in the world a kind of novel writing implement, has much advantage, is known as cross-centennial writing implement.A Neutral writing ink full name " aqueous pigment medium viscosity ball pen " is that the nineties is taken the lead in beginning to put on market by Japan.So-called " neutrality " is meant its ink viscosity circle between the viscosity and aqueous ball point ink viscosity of oiliness ball pen ink, and it writes lubricated smooth, and ink marks is restrained strong, can do permanent preservation, also has characteristics such as ink flowrate is even simultaneously.Existing now a lot of countries produce, and comprise China.In recent years, write in China commonplace with gel ink pen.The gel ink pen ink has neutral viscosity because of containing the composition of resin glue pledge, has any different with other ink.Writing not only can absorb ink paste seal literary composition after forming on the paper, and ink paste seal literary composition also can overall absorption gel ink pen writing.
1, write the feature of afterwards impressing earlier: the first, see through red seal literary composition and find that the writing lines are more complete, it is disconnected not take off.The second, be covered with one deck red ink paste on the writing lines.The 3rd, the reaction of writing lines is fuzzy.
2, the feature of impressing earlier and afterwards writing: the first, the writing lines are more complete on the seal literary composition, do not take off disconnected or rare phenomenon.The second, though the part redness is arranged in lines thoroughly, black lines reaction on the seal literary composition is apparent in view.The 3rd, the writing line color does not change.
Because the black gel ink pen is write and no matter successively printed civilian juxtaposition, its lines are all more complete, in the feature reflection not clearly, so when checking, mainly compare from the sharpness of writing lines.In addition, the gel ink pen ink has varied, different ink and seal some different features may occur behind the civilian juxtaposition, so when checking, it is right to carry out aspect ratio targetedly.
(4) blue ballpoint pen writing and the feature of printing civilian sequencing
Blue ballpoint pen oil mainly contains oil-soluble dyes, just can absorb red ink paste after writing, and still, promptly writes after red ink paste is impressed, and ink paste just can not absorb ballpoint pen oil fully, must treat could absorb ballpoint pen oil after the ink paste drying, and its feature is as follows:
1, write the feature of afterwards impressing earlier: the first, the ballpoint pen writing lines do not change.The second, the blue ballpoint pen writing line color at the juxtaposition place changes, becomes black by original blueness.
2, the feature of impressing earlier and afterwards writing
Ink paste seal literary composition forms the back because can not be dry immediately on paper, thus write under the undried situation with drying after write on feature different.
1. be writing feature after impressing: the first, the ball pen lines rareness can occur or take off disconnected.The second, in stroke and seal civilian overlapping outside writing lines, have the composition of a little red ink pastes.The 3rd, the color of blue ballpoint pen writing lines becomes black by original blueness at the juxtaposition place.
2. print the feature of writing after the civilian drying: the first, the ballpoint pen writing lines do not occur taking off disconnected or rare basically, and lines are more complete.The second, can not have the composition of red ink paste in the civilian overlapping outer lines at writing and seal.The 3rd, the writing lines are varied to black by original blueness.
No matter ballpoint pen writing and Yin Wen write bonnet earlier, still to cover afterwards earlier and write, the color of its lines overlapping all can be transformed into black from original blueness, and its difference is: the ballpoint pen writing lines of writing after impressing are reflected on the Yin Wen more significantly.The ballpoint pen writing lines flow direction of afterwards writing because impress is earlier write the writing lines of afterwards impressing relatively earlier and is flowed to clear much obvious.
(5) two blue carbon paper duplication handwritings and the feature of printing civilian sequencing
Two blue carbon papers are commonly called as the blue paper of seal, and its employed history is long.Two blue carbon papers are meant double side blue transfer paper.It contains composition and mainly contains oil plant, wax material and pigment.The transfer paper writing can absorb ink paste seal literary composition, and ink paste seal literary composition can not overall absorption to duplication handwriting.Two blue carbon papers are the copy number connection simultaneously, and the writing lines of transfer paper manifolding all are that point-like is formed by connecting, and with other writing lines obvious difference are arranged.It with seal literary composition overlapping after, its feature is as follows:
1, write the feature of afterwards impressing earlier: the first, the writing lines do not change.The second, the color of writing lines is varied to black by original blueness.The 3rd, the handwriting lines are fuzzy.
2, the feature of impressing earlier and afterwards writing: the first, handwriting lines rareness.The second, the color of writing lines also is varied to black by original blueness.The 3rd, the writing lines are more clear, do not produce writing lines hazy sensations.
