First, before the restoration, the craftsman will inspect the poster to determine whether it can be repaired. After the decision, he will dissolve the adhesive of the tape with the solution and slowly remove the tape. Then, each poster will not be separated by a plastic net, which can prevent them from sticking to each other in the bleaching solution, and the solution will also make the antique poster show its original color. Now, craftsmen squeeze out the bubbles between the layers of the poster, air-dry them on the internet, and then stir them into a paste with water, wheat and cover powder.
Second, calcium will neutralize the acidity in antique paper, thus reducing the speed of wearing out posters. The craftsman applied the mixture to the huge acid-free paper with a brush, and then applied a layer of the mixture to bond the cotton cloth and the paper together. At this time, a piece of paper with a cotton bottom was made. Then the craftsman will carefully stick the poster on the cotton paper within the specified time, and then use tools to perfectly combine the four posters. Now the craftsman is looking for a piece of paper similar to this poster in a pile of scraps of paper to repair the broken corner of the poster. Then use a piece of transparent paper to describe the shape of the fracture. Draw lines, cut pieces of paper and make a new corner for the broken poster.
Thirdly, in order to make the edge of the paper thinner, the workers will grind it with sandpaper, then apply a layer of glue from the plant base, glue the damaged part, and then flatten the new corner with a wooden stick to make it highly consistent with the damaged poster. Now craftsmen need to repair damaged images, and the most difficult thing is to prepare pigments that match the color of antique posters. Sometimes it takes many attempts to integrate the restoration with the poster. Then the craftsman repairs the broken line with a watercolor pen, and different efforts are needed according to the specific situation. With years of experience, he will make flaws and creases disappear. After all the details are handled, he will cut off the four sides of the poster and check for imperfections. From a tattered poster to a new print that looks like it has just been taken out of the oven, this antique poster has now become a short history preserved by future generations.
The poster is wrinkled. How to flatten? The specific operation method is as follows:
Tools: three heavy objects, posters, water.
1. Place the poster on a flat and hard surface and smooth out the obvious wrinkles by hand.
2. Then find three heavy objects. Put the slightly wet poster on a heavy object, and then press another heavy object on the poster.
Finally, put a flat weight on the poster to completely cover the paper.
4. Open the inspection poster every day until it is dry. It takes three to four days for the wet poster to dry completely. When it is dry, the poster will become flat and most of the wrinkles will disappear.
Precautions:
1. If the poster is printed with water-based ink, this method is not suitable.
2. Wet the poster slightly with water. Too wet will cause the poster to break.
It is suggested to cover the wet poster with a layer of plastic wrap for protection.
4. Don't separate the poster from the absorbent material directly by hand after taking it out. Violence may damage posters, so be careful to separate them.
Extended data
In the stacked state, the paper will produce "flounces" or "tight edges" with the change of humidity. It's easy to wrinkle when printing.
The bow fold caused by "lotus leaf" is at the end of the paper; The bow wrinkle caused by "tight edge" is not fixed, because the four sides of the paper are tight, the middle temperature is high and convex, and the paper will move irregularly under pressure.
Humidify the paper before printing, and the temperature and humidity in the workshop should be appropriate. For "flounced" paper, paper drying method can be used.
How to remove the crease on the poster? Go to the studio shop, where you can buy an easel with clear slate! Then put the poster in! It takes two to three days. But the crease can't be erased! You can't tell if you don't look carefully! It would be nice if we could find. 1003 sponge glue. But we haven't seen this glue here for years! If you can buy it and paste it on the back of the poster and color it, you can remove the crease. Two things are more than ten dollars! Good luck!
