What is Block Printing?
The oldest type of printing which is in trend from many centuries is Block Printing. There are many evidences which show that block printing existed from 5th century but working on block printing started in 15th century. It is popular in all corner of the world but its roots are in India, Japan & China. Hand block print is widely popular among several people round the world.
Block printing has a very long history and variety of techniques are used for it but most popular technique is one in which carved material is immersed in ink and then image is transfer on piece of paper & fabric. It can be used on different types of materials like wood, rubber or linoleum. I prefer linoleum for work.
Printing done on images using this technique are very bold if compared with other style of printmaking. As carving is done by hands on the blocks so texture has more prints and detail is very less. If you use knife for carving there may be possibility that blocks can be carved with a detail.
Another name for block printing is relief painting as ink used for printing leaves texture which is raised on piece of paper. Note one thing that letterpress and block printing both are different as in letterpress enough pressure is applied on the image so that an indent can be leave on paper. Hand is used in block printing due to which ink sets on the surface which gives raised look texture to the material.
Process of Printing
The initial step involved in printing is designing the sketch. It is very essential that image should be reversed if text is using as image get reversed on the block. Once the image gets ready it is then transferred on material which is linoleum so that I get an outline where carving has to done.
Next step involved is designing of carve. I always do one thing that part which doesn’t need to print is carved away as ink is applied on the surface which is raised for printing of design. Surface which remains untouched will be imprint on the paper. Time taken for carving is not fixed depending upon the measurement & details of the image. Time required for carving can be an hour, lot of weeks or months.
Variety of knives is used by me for different purpose like small tipped knife is used for carving the details & its carving. Larger knives are used to cut the background. Patience is required to carve the block as if hand slips out whole piece can be ruined. With proper practice it can be learn that how much pressure is required to carve and try to learn some best techniques for complex designs.
When block gets carved excess part is trimmed out using scissors so that straight edge look can be given, after this piece gets ready for print. Variety of inks is available in market but it should be test before using to get best 1. I generally use oil based type ink as they are good for fabric & paper both. You can go for other options also.
Whenever I go for printing process ink is squeezed in small amount by me in a glass or different plexi glass piece and then rolled out in using a roller. This helps me in getting a thin and even layer so that ink can be applied properly on block.
Then ink is rolled on the block but I always make sure that block should be thin having an even layer. Then block is taken by me and I pressed it on the piece of paper or other fabric. Pressing can be done either by hands, rolling pin, printing pin or printing barren. (Which is a tool used for applying pressure on the block) Always remember that pressure should be even.
Important part in the block printing is pressure should always be even as if pressure will be uneven then in some part color can be dark and in some part it will be fad. This requires practice so that you can become perfect.
It takes several days for ink to become dry just like other process of printing. You have to wait for long before using the prints. Ink based on oil takes time for drying from 2 days to many weeks while water type inks dry little bit faster. Inks are ready in such a way that they can dry slowly which helps you in printing process when ink not dry. If ink gets dry little bit faster you will get a uneven details coverage.
