Clear images, bright colors

The main purpose of EloChrome is to depict vibrant images by producing more accurate colors and offering a wider color gamut compared to a standard CMYK printing process.

Colors created by mixing of 2 or 3 EloChrome inks can be clearer, stronger and brighter when compared to printing with a single spot ink.

Converting colors

Artwork can be delivered using CMYK and/or Pantone spot colors. In all cases, our pre press specialists will convert the delivered colors into EloChrome color build-ups. At the same time we pay special attention to matching the delivered values and/or color targets as closely as possible. Some spot colors, however, can be difficult to match using a standardized extended gamut system such as EloChrome (e.g. pastels, fluorescents and metallics).

We encourage you to contact our repro specialists if considering the use of such tints.

Pantone Guide is used for color matching. The target spot color needs to be available in the Solid Coated Pantone Plus Series Formula Guide.

Process-specific requirements and challenges

Trapping

Even in a high-performance print process such as litho some register variation may occur. Trapping or cutback is applied in order to prevent visible color-to-color register deviation and unsightly white lines in printing. The term trapping relates to instances where two colors meet. The lighter color is slightly expanded into the darker to create an overlap. This yields a darker outline.

Trapping cyan

Designers are not required to make allowances for trapping in the supplied artwork. Elopak will ensure that the correct process-specific trapping is applied where necessary. Depending on design complexity, trapping or cutback may vary from 0,10 mm up to 0,20 mm. 

Adherence to print specification allows Elopak prepress specialists to correctly apply trapping and avoid the side-effects of print-to-print registration variance.

Text requirements

Text can be defined either in a single pure EloChrome color (the safest choice for small texts), or in a combination of colors (maximum 3 colors).

For single-color positive text, we require a minimum 5 pts sans-serif font (minimum line width 0.15 mm). For multicolored text (maximum 3 colors) and negative text on a single-color background, we require a minimum 6.5 pts sans-serif font (minimum line width 0.2 mm). Negative text on a multicolored background requires an 8 pts sans-serif font (minimum line width 0.25 mm). We recommend that text be as large as possible to ensure optimum legibility.

Important

All text in the supplied artwork must be converted to paths or outlines. For contingency, please include all used fonts in the delivered artwork package, in case of text corrections at a later stage.

Images and vector graphics

Logos should be delivered as vector graphics. Please make sure that logo text size and line thickness is within the required print specification.

Preferably, images are to be delivered as either .tiff or .psd files, using CMYK color space, and should not be color managed (color profiles need not be embedded). Minimal required resolution is 300 dpiSee more. Please leave image layers unflattened.

Target prints

If there is a demand for reference color match, a hard copy must be supplied together with the relevant artwork.

If no target print is supplied, the reproduction result will be based on standard Elopak color and dot gain profiles.

If a Pantone Guide is to be used for color matching, the target spot color needs to be available in the Solid Coated Pantone Plus Series Formula Guide.
