In the world of printing two methods are mainly used and that is litho print and the other one is the digital print. Though both the printing methods are famous but both of it use different technologies. Both of these systems have different pros and cons that are linked with these. In ancient time people used this Litho Printing on silk by using carved wooden blocks. The ink had been applied directly to the blocks (made of wood) before they were transmitted onto the materials.
Different materials used in litho printing
In earlier days Litho Painting meant an image drawn with wax, oil, and fat onto the flat surface of lithographic limestone plate. The stone had a delicate mixture of gum and acid, and then the drawing had been done on the stony portions which were not protected by the grease-based image. The water was retained in the etched areas of the stone and the stone was consequently moistened thereafter they used an oil-based ink that would repel the water.
Modern Litho Printing
With the advent of technology, Litho Printing has changed its meaning. Today lithography is different from the original ones. In the modern age, a plate is used in litho printing which is either etched or engraved or marked with many small dots to hold the printing ink and letterpress or wooden block printing is used to the raised surfaces of images or letters. You will find this type of printing in high-volume books or in magazines particularly where the colour is needed to illustrate. This type of printing has become very common since the 1960s.
Benefits of Litho Printing
With the development of technology digital printing technology brings technical advancement. Today you can get exciting, new, different features and more options for commercial printing. You have to understand and distinguish the advantages and disadvantages of digital printing. It is definitely critical to compare the traditional offset printing with digital printing. You can find the high volume commercial printing technology in offset lithography or Litho Printing. In such printing, the desired print image has been burnt on the plate and thereafter it is transferred from the plate to a rubber blanket and at the end, it is transferred to the printing surface and is also based on the retaining of oil and water. The image or letters that are to be printed get ink from the ink rollers. Whereas the non-printing areas holding the film of water, so that these areas cannot get the ink remain ink-free.
Features of Litho Printing
- High image quality
- Works on a wide range of printing surfaces like paper, wood, cloth, metal, leather, rough paper and plastic
- The unit cost goes down as the quantity goes high
- Quality as well as cost-effectiveness in high volume jobs. Today digital presses are almost going to close due to its cost or benefit ratio. But the offset printing is going high for its high-quality work.
- Digital printing is not able to compete with the volume that the offset press can produce
- Many offset presses use computer-to-plate systems as opposed to the older computer-to-film workflows, further increasing the quality.
Thus there are many advantages that you can get from litho printing or offset printing. If you are having any requirement of printing then you should go for this litho printing.
