In previous articles on color management, the factors that affect color output were explored. In this, the fourth in a series on color management, we explore what can be done to consistently and predictably produce accurate color. A good color management strategy requires an understanding of factors impacting color output, then managing those factors to ensure consistency.
The Printer
Your printer should be well maintained and calibrated regularly. If your printer has adjustable heaters, be sure to match the temperature of the heater and dryer to the media manufacturer’s recommendations.
Ink
Every printer manufacturer provides ink that is formulated for optimum results on their printer. We recommend the use of a name brand ink. Though aftermarket inks are less expensive, consistency between batches may be problematic.
Media
Profiles should be created for each media type used. Profiles should be generated in moderate temperature and humidity. Ideally, make note of the temperature and humidity at the time the profile is created and create a separate profile if warranted by significant and uncontrollable shifts in environment.
Environment
A hygrometer should be used near your printer so you can monitor humidity. If humidity drops significantly, a humidifier should be used to raise the humidity to acceptable levels. If humidity increases, your air conditioner will help stabilize the humidity level.
Production Equipment
Every device you use in the design and production of digital prints should be profiled. This includes your monitor, scanner and each media type you print to. If your monitor is not profiled, your design on screen will not appear correctly, and you may be prompted to make unnecessary adjustments. If you are in the habit of regularly profiling your equipment, color will be presented consistently throughout, and you won’t have to wonder where you might be off.
RIP – Raster Image Processor
For the most critical jobs, familiarize yourself with the capabilities of your RIP. Your RIP may have features to make it easier to match specific colors. For example, Roland’s VersaWorks allows the creation of libraries for spot colors and special colors. To populate a spot color library, a color spectrophotometer can be used to scan color samples from a Pantone swatch book.
With an understanding of the many factors that can affect color output, you are better equipped to develop a process to ensure consistent and predictable color output.
