Each color space has a defined gamut - a range of possible colors. There is no single color space that can reproduce all the colors from the entire spectrum whether working in CMYK (Cyan, Magenta, Yellow and Black (which printers call "Key") or RGB (Red, Green, Blue).

CMYK color spaces typically have color gamuts that are slightly smaller than RGB spaces. That means fewer colors, and usually less vivid colors. The benefit, however, is that a color space such as SWOP CMYK has a color gamut that is achievable by almost all CMYK printing devices. This is helpful in terms of color consistency if jobs are to be printed across different print devices. Keeping to a CMYK color space for line art or vector art can also improve the match from image color to spot color (such as PANTONE) and preserving or editing the black channel is also possible when the color space is CMYK.

RGB color spaces are generally larger than CMYK spaces and able to reproduce more colors that are brighter and saturated in color. RGB color spaces are the preferred color space when jobs are sent to the printer. Keeping files in RGB allows for greater variety of output options, such as web, press or digital print. RGB also means smaller file sizes, which can increase productivity. Most print devices use CMYK inks, however, so at some point the RGB elements will be converted to CMYK. The print shop can generally do the conversion at the RIP just prior to printing, which generally yields the most pleasing results.

Sometimes it's possible to design artwork using CMYK colors to yield more precise matches and yet keep images in RGB spaces in order to retain more vivid color. RGB and CMYK elements can then be placed into page layout applications such as QuarkXPress or InDesign and then be output in such a way that none of the colors get converted until they should be, at the printer.

Soft proofing is often used by both designers and prepress operators to make color critical decisions on the monitor. Computer monitors use the RGB (additive) model to display colors. In order to display correctly, a captured image is translated into pixels (picture elements) that can be projected as rays of red, green, and blue light. Digital presses use the CMYK (subtractive) model to produce colors. Cyan, magenta, and yellow dry ink is placed on white reflective paper. Each then absorbs, or subtracts, its opposite color from the white light that it reflects back. Black (K) is primarily used to change the color's luminosity value (lightness or darkness).

As a result, you will see differences in color from one monitor to another and differences in color from the monitor to the printed output, due to the different the different mediums used for viewing a job (monitor v. ink on paper). The accuracy of color depends upon your specific monitor. We've made every effort to represent images of products accurately. Due to the wide range of computer monitors and color displays, you should consider the colors you see on your screen to be representational.

For the highest quality output...

• All images should be edited, rotated, cropped and sized in an imaging software application such as Adobe Photoshop. Do not resize, crop, rotate or adjust images in page layout applications if possible. Place images into the page layout at 100%.
• The recommended image resolution should be no less than 300dpi at the actual finished size. Scale images with bicubic sampling and crop all images in Photoshop. Do not use page layout applications such as QuarkXPress, or InDesign to make image size adjustments
• Submitting images with higher than needed resolution adds unnecessary processing time, creates larger files and may degrade image quality.
• Do not include transfer functions or screen angles unless directed to do so by the print provider. If the job requires specific screen angles or transfer functions, make sure to consult with your print provider to create the best results.

Currently, Janzoon.com supports the following file formats for uploaded designs:

• JPEG Image^* (.jpg, .jpeg)
• GIF Image (.gif)
• PNG Image (.png)

*For JPG, keep your files in RGB format. Also, be sure to save your files at the highest quality settings (10 -12). The JPG file format lends itself for high quality images with small file sizes.

For optimal results, use clear sharp photographs. Do not increase the physical size of your image before uploading it. This will degrade the quality of the image and make it fuzzy. Try to upload an image that you can reduce in size as this will result in a much sharper image the majority of the time.

Resolution determines the quality of your image. A high-resolution image is clear and shows more detail, so it will reproduce better on your Janzoon products. Image resolution is measured in pixels.

Back to top

Pixels are tiny colored dots that make up photos and images. An image becomes sharper as you decrease its size. Your image must be at least 72 dpi (dots per inch) in order to be uploaded.

There are three size requirements for Janzoon products:

1. Files must be at least 432 pixels wide and 432 pixels tall.
2. Files must be at least 72 dpi (dots per inch)
3. Files must be under 5MB in file size

The ideal programs to use to create your business card image are Adobe Photoshop, Adobe Illustrator, Adobe InDesign, Quark, or Corel Draw. Once you have designed the card you will want to convert it to one of the following formats: JPG, JPEG, GIF or PNG.

One way you can convert your file is by exporting or saving it as an eps file and then importing that eps file into Adobe Photoshop. You would then choose the following settings: 300dpi and RGB color. Be sure your file size is 3.54” x 2.05” (or 2.05” x 3.54” in the case of a vertical card design). Once the file has been imported you flatten the image and save it as a JPG.

If designing in Adobe Photoshop you can save the file directly out as a RGB JPG.

A shift in color may occur when using a CMYK or pantone color format. To avoid unexpected color shifts, convert your image to an RGB format, and make color corrections before uploading your file.

Your photo may not upload for the following reasons:

1. The file format is incorrect. The formats allowed for Janzoon products are .JPG, .JPEG, .GIF and .PNG.
2. The image size is too large or too small.
3. The file size is too large. Files must be 5MB or smaller.

Paid images will be retained within My Account under My Images. Unpaid images will be removed after 3 weeks; a notice will be sent 1 week prior. Used removed images will be invalidated.

Images are limited to production by Janzoon on Janzoon products. Images cannot be downloaded for any reason. Images cannot be incorporated into a logo, trademark or service mark. Any images featuring a model that are used in a manner that would lead a reasonable person to believe that the model personally uses or endorses a product or service or portrays the model in an unfavorable or overly controversial way, must include a statement indicating that the person in the image is a model and is only being used for illustrative purposes. No images may be used in a pornographic, defamatory or otherwise illegal manner, whether directly or in context or juxtaposition with other materials.

Two very important things you want to AVOID:

1. A white border around the edge of your image.
2. Cutting off any important areas of you image.

Trim is the final dimensions of the paper once it has been cut. Trim marks indicate where the cut will be.

Bleed is an image that goes to the edge of a piece of paper. Having a bleed prevents your image from reproducing with a white border.
