A Comparative Analysis of Digital and Offset Printing

The sexual climax of the traditional opinion was a great reform in the melody community. Although a need was constantly felt for a print device which after part eke the imprint process of short-run four-color jobs. Before the earned run average of the digital imprint wave in shape of Indigo, Docucolor and Heidelberg, the task was a dream for e genuinely business organization as the printing with four colors at small scale was very expensive and inefficient to print. With the invention of digital printing technologies the printing was revolutionized and new standards of improved printing feel in a represent-effective manner was settled. The digital transformation wave included valu fit products such as Heidelberg Quickmaster DI. The invention of the digital stub out includes cost effective and production efficient products such as HP Indigo and The Xerox iGen 3, which fulfilled the long lasting needs of the businesses.Offset PrintingWith the advent of the digital printing although the printing process is revolutionized but this has not effected the importance of the traditional strike down printing. It is a guessing that the traditional offset printing will become obsolete in future but silence it will take years. The importance of the traditional printing depends upon the nature of job as some printing jobs are over sized and stubnot be undertaken through using a traditional press.The choice of the applied science depends upon the nature and specification of the job. In order to choose the most effective and relevant engine room, it is important for the charge to choose right and cost effective printing solution for the business with the consultation of specialized printing consultants. (Digital Synergy, 2007)Comparison between Digital Printing and Offset PrintingWith the introduction of advance array of printing devices the sloppiness has also increased. In order to make a choice between the digital and offset technology it is important to u nderstand the characteristics and performance of both the technologies. The printing device with to a greater extent suitable options related features should be chosen in order to find the most appropriate commercial printing device.Method of printing in Offset PrintingOffset lithography is the most common high volume commercial printing technology. In offset printing, the desired print find is burned onto a plate and is then sellred (or offset) from the plate to a rubber blanket, and then to the printing surface. The lithographic process is based on the repulsion of oil and water. The image to be printed gets ink from ink rollers, while the non-printing area attracts a film of water, keeping the non-printing areas ink-free.Mechanical Steps Eliminated in Digital PrintingDigital printing eliminates many of the mechanical steps required for conventional printing, including making films and color proofs, manually stripping the appends together and making plates. (Pinsonnault Creativ e, 2007).Advantages of Digital PrintingThe advantages of the Digital Printing technology includesShorter turnaround. Same leave alone in case of highest and broken inest no. of prints. Through digital printing the accurate numbers of prints washbasin be produced with a least amount of wastage and least variation as liken to the Offset printing techniques.Low costs for high volume printing , although the cost per unit is much more than that of the offset printingCheaper low volume printing. While the unit cost of each piece may be higher than with offset printing, when setup costs are included digital printing provides lower per unit costs for very small print runs. Variable Data Printing is a form of customizable digital printing. Using culture from a database or external file, text and graphics can be changed on each piece without stopping or slowing down the press. For example, personalized letters can be printed with a variant name and address on each letter. Variable data printing is used primarily for estimate marketing, customer relationship development and advertising. Advantages of Offset PrintingHigh image quality. Works on a wide range of printing surfaces including paper, wood, cloth, metal, leather, rough paper and plastic. The unit cost goes down as the sum of money goes up. Quality and cost-effectiveness in high volume jobs. While todays digital presses are about to the cost/benefit ratio of offset for high quality work, they are not yet able to compete with the volume an offset press can produce. Many modern offset presses use computer-to-plate systems as opposed to the older computer-to-film workflow, further increasing quality (Pinsonnault Creative, 2007).The one, true choice for offset digital qualityThe HP indigo is specially designed in order to meet the quality and color processes collect of offset printing. The easy and instant to dry quality of the ElectroInk used in Hp indigo provides it with snip edge as compare to other tec hnologies. It is best suited for commercial printing, as it is relatively cost savvy and efficient in production. The quality of printing is very eye catching and impressive and can be used to attract the customers with a demand of high quality vivacious images.The technology has elevated the standard of the print quality, as the advanced pressing power of HP indigo is much more superior as compare to other competing technologies. The ElectroInk ekes the technology with the production of image with higher resolution, sharp images and vibrant colors. The machine provides the users with the choice of optional 5 and 6-colour inking stations with the luxury of white ink and special concealed inks best suited for the corporate printing. The Hp Indigo provides an extended array of colors as compare to other digital print technologies.CriticismEarly incarnations of the press were prone to suffer from banding and ink friendship problems, however with newer models these issues have been resolved and would only be seen in unusual circumstances, for example if the operator had the press incorrectly configured.Although, there is still a natural band about 100mm from the trailing edge which can only be seen when printing some colors. To help reduce the band you should adjust the 2nd transfer gap and make sure the press is well greased and lubricated. (Wikipedia, 2007)
