Example Embodiment

[0010] The process flow of the present invention will be further described in detail below.

[0011] 1. Film production:

[0012] Put the photos to be produced in the scanner for scanning, and do some simple processing such as pasting, cutting, and adding lace to the scanned images in the software Photoshop or CorelDRAW, and save them as "TIF" format files, and then in the "Founder Raster Image Processor" hangs the screen to output the film of 25-40 mesh dot version.

[0013] 2. Printing:

[0014] Shellac with absolute ethanol (C 2 h 5 After OH) is dissolved, add potassium dichromate (Cr 2 K 2 o 7 ) or ammonium dichromate ((NH4) 2 Cr 2 o 7 ) mixed evenly is shellac photosensitive glue, and then the photosensitive glue is evenly coated on the stone surface. The coating method is to first pour the photosensitive adhesive on the stone surface and place it in a centrifuge to rotate for 3-5 seconds to coat evenly.

[0015] Place the photosensitive adhesive-coated stone i...

Abstract

The invention relates to a method for etching a photo on marble, which can originally reflect an etched object and comprises the following steps of: outputting an image produced by scanning a photo which needs to be manufactured into a film with 25 to 40 meshes of dot grid; dissolving shell-lac by absolute ethyl alcohol (C2H5OH), and then evenly mixing to obtain a shell-lac photosensitive resist; evenly coating the photosensitive resist on the surface of the marble, on which the photo needs to be etched; tightly sticking the film on the surface of the marble; irradiating for 2 min under ultraviolet lamp light; then developing with alcohol until the image of the film is developed on the surface of the marble; printing off stone with the image, and etching by adopting corrosive liquid; after etching, washing the photosensitive resist on the stone by weak base water (NaOH and H2O) prepared in the volume ratio of 1:100, and then washing the residual base water by clear water; spraying pigments to the etched surface of the marble; after the pigments are completely dried, lightly rubbing out the convex pigments by a millstone; and when the convex pigments are completely rubbed out and only the pigments on a concave surface are left, obtaining a clear black-and-white photo.

Description

technical field [0001] The invention relates to a method of etching photographs on marble. Background technique [0002] How to preserve people's photos for a long time, so that people in the future can see the real present, many people are using their brains in this regard. Anyone who has been to the cemetery will find some various photos, some of which are printed on porcelain and fired; some are printed on inkstone with modern laser technology; statue". However, how long the current porcelain statues can be preserved in the wind, sun, and rain cannot be verified for the time being, but they only appear on one plane, and they never have the meaning of "carved steles and stones". As for the photo made by the laser on the ink stone, it is undeniable that its accuracy is very high, but it is still only the shadow of the ink stone formed by changing the color of the stone surface. As for the "shadow carving" made by skilled craftsmen, it can never be separated The era backg...
