If you still lived in the early days of printing then this question would have never crossed your mind because two color offset printing was the only option available in those times. With the growth of digital printing technology there are new options available now for commercial printing. Four color digital printing is a viable option for all the marketers in today’s times. But the availability of the two color and four color printing process has left many people confused. This is the reason, understanding the advantages and disadvantages of both these color printing processes is important.
Two color offset printing is one of the most common processes for high volume commercial printing. In this process the image to be inserted is placed on a plate and then transferred from the plate to a rubber blanket, which again is moved to the printing surface. Two color printing is mainly based on the use of oil and water. Ink rollers supply the required ink to the images while the non printed area attracts a film of water. The film of water keeps the non printing area free of any ink. In four color digital printing process the mechanical steps such as manually stripping the pieces to create a plate and making films for color proofs are not needed.
Now, let us take a look into the advantages of both these processes to make a comparative study:
Four Color Digital Printing Advantages
- It provides a shorter turnaround as it does not require much manual work.
- All the prints have same color. There are lesser wastes, accurate counts and the color remains constant as there is no need to balance the ink and water during digital printing.
- It costs lower for high volume of printing. Though the per unit cost of each piece is higher than in offset printing, but when you consider the set up costs, you will find that four color printing costs much less nowadays as the there is no setup cost in digital printing.
- There are customization options in four color printing without slowing down the print speed. The information stored in the databases can be used to provide unique copies every time, such as ones for the personalized letters used for marketing. This process is called Variable Data Printing.
