5 Business Considerations for Color Quality Assurance Software

Monitor Color Quality Worldwide: Cloud based color quality assurance software allows organizations with multiple presses and print facilities to remotely manage and monitor customer jobs via the Internet or the firm’s Intranet. This provides the ability to remotely monitor the color quality of multiple jobs in real-time, in multiple locations, using a, smart phone or tablet or network connected computer. The software thus enables: excellent color reproduction quality throughout an entire print run accurate and…

Full Vision Print Inspection System or Inline Spectrophotometer for your Web/Flexo Press? 3 Things to Consider

Competition in the print industry is fierce and profit margins are thin. As a result, companies have to be diligent when making capital equipment purchases. When it comes to equipment that helps maintain inline/continuous print quality for every print impression, costs can range from $30K for an inline spectrometer or densitometer to nearly $300K for a full vision print inspection system. Which one do you need? That depends. Here are three things to consider before…

Pressroom Automation and the Difference Between Open and Closed Loop

Automated Measuring Systems Scans instead of individual measurements Scanning spectrodensitometers measure the entire ink control strip thus recording all ink zones in one single measuring operation. Since the printer no longer has to select arbitrary ink zones, he does not miss the problematic ink zones either. He can now be certain that all possible inking fluctuations are detected. In this way, therefore, automation at the same time eliminates all subjective influences. As in handheld instruments,…

A Functional Comparison of the Densitometer and Spectrophotometer

In deciding on the appropriate color measurement instrumentation, it is essential that you understand the operational characteristics, functional comparisons, and intricacies of both the densitometer and the spectrophotometer. This is best communicated in the in-depth instrument descriptions below. Densitometers Density is a measure of the absorbance of an ink at specific wavelengths of light. As an example, yellow ink has a maximum absorbance in the blue region, so its density is calculated using a filter…
