Technical specifications

Better color managment

All our images are in RGB mode, wich means they are in red, green and blue, these three colors are the so-called primary additive colors that are used by computer monitors.

For the printing procces you will need to convert the file to a CMYK. This means cyan, magenta, yellow and black, which are the colors traditionally used by the printing industry, combining the three primary subtractive colors with black (using "K" instead of "B" avoids confusion about whether it is blue or black) to produce what is normally refered to as four-color printing. Because of the variety of real-world color separation and printing processes, it's difficult to create a truly universal CMYK file.

Scanners, color monitors, proofing systems and presses all represent color differently. Each of type of device uses its own "language" to interpret and render color. And each individual device, because of its unique characteristics (such as age, temperature, light exposure, etc.), has its own "dialect" of that language.

If you are unfamiliar with this process, we recommend you to follow these simple steps.

1. You need to callibrate your monitor
*Set up the profiles supplied with your monitor.
*Use a monitor calibration software such as:
Colorific (PC or Mac ) www.colorific.com or
ColorSync (Mac) www.colorsync.com (ColorSync calls upon the computational power of "CMMs" (color matching modules) which converts images from one color space to another-for example, from RGB to CMYK-and simultaneously apply the information in the profile to correctly render the image.)

2. Use ICC profiles
To build a common foundation for communication of color information, the International Color Consortium establishes base-level standards and protocols in the form of the ICC Profile Format specifications. Ask your supplier for an ICC profile of their output device and place it at the system level in your computer. This profile can be identified by Photoshop and applied to any RGB scan www.color.org

For all professional uses we do not recommend using the default settings in Adobe PhotoShop.

Sharpening Your Image
 Our images do not have a final sharpen, we think it is best for you to add it once you are ready for your output. The amount of sharpness you apply to an image depends on your output. For optimal sharpness effects, we recommend you use Unsharp Mask because it offers the most control over the other variables that affect sharpness.
