Technical requirements

An acceptable digital original:

  1. conforms only to PDF/X-1a:2001 (ISO 15930, PDF ver. 1.3) requirements, i.e. a print-ready composite PDF with either CMYK or CMYK and spot colors, according to the order
  2. is prepared in Acrobat Distiller 5 or 6 from a Postscript print file using approved settings; and which has undergone preflight control, as recommended
  3. has a 3-5 mm bleed, the pure print format is centered on the PDF page, lacks cutting marks or includes these marks at a minimum 3 mm outside the format, has proper picture resolution and color separation according to the printing process, is given a file name that enables identification of the item's title, includes page numbers within the given file and has been created in a manner that follows all other generally recognized rules for print-preparation.

A folded and clasped or otherwise sealed sample layout is necessary in order to perform a visual check on digital originals and layouts, according to the final result (this includes covers, inserts, etc).

Digital color proofs must be equipped with a control scale (a full area for each color and also a raster in halftones and three-quarter tones), as well as with information on each ICC profile used.

Digital originals are accepted on data storage devices, via e-mail and also FTP.

 

Special print shop requirements

 

A readied-project folder is located on the FTP server at: ftp.moden.ee/ (username: ftp.moden.ee; password: Moden1); users are permitted to create sub-catalogs and save files. Erroneous files must be resent using a new name, since only we are allowed to access, delete and rename files.

Overprint is automatically added to all black objects and removed from all objects of other color during preflight. Non-overprint black (see below) should be used if black overprint is not desired. A special agreement with Moden is necessary when using overprint as a design style.

Recommendations

 

3–5 mm bleed


All objects that reach print-format must extend across the edge by 3-5 mm so that white space may not be visible as a result of folding, binding, cutting or other offsets. It is important to take bleeding into account already when preparing the design elements and framing images, otherwise a significant portion may be cut off. The bleed requirement also applies to advertisements that extend to the edge of a page – clients must make sure that important elements are situated no less than 3-5 mm from the edge of the page. Lines running parallel to the edge of the page can show even the tiniest post-processing mistakes.

 

Black color and overprint

We add overprint to all black (100% K) objects during preflight in order to avoid the most miniscule print precision errors becoming visible around black text, lines and smaller objects set against a color background. Non-overprint black should be used in the case of black objects for which overprint is not recommended (i.e. large areas set above a picture or color that might glare through):

  • regular black (triggers automatic overprint): 100K
  • rich black (mixture of solid black and one or more CMYK colors): 100K-50C or 100K-50C-40M
  • non-overprint black: 100K-1C-1M-1Y

Another common overprint problem is when the feature is unintentionally added to objects that are white or colored, as a result of which text can disappear or colors change. It is recommended to remove overprint from all non-black objects when preparing rasterization.

The print shop should be informed if the project implements trapping, overprint on non-back objects, or if the client has any other special wishes for overprint application. Both parties can then reach an agreement on project details.

 

White text on a black background

 

Since 100% K black tends to seem too bright when covering a large area, rich black (which incorporates black with other shades) is often used in design. Even the tiniest print precision error makes text illegible when printing white letters onto such a background (the same applies with a dark picture or color background).

Minimum 10-point font is customary when using serifs, cursive or fine lines; 8-point font is common for text without serifs. Either 100K50C or 100K50C40M should be chosen when using rich black: both types guarantee nearly maximum darkness (richness) in the printing process.

A non-overprint black (100K-1C-1M-1Y) outline measuring 0.1-0.15 mm set behind text also helps to reduce print precision problems when white text is situated on a rich black background.

Image signatures: The simulator added here shows a 0.035 mm offset with Helvetica and Helvetica Bold 8-, 10- and 12-point font on 100K, 100K50C and 100K100C100M100Y backgrounds. According to ISO 12647-2, offset printing up to 0.08 mm is allowed for an image centered on B2-format paper over 65 gsm; up to 0.12 mm is permitted in other instances.

 

Color separation

 

'Color separation' signifies the transmutation of a picture initially in RGB color scheme used by a scanner, digital camera or other input device into a color scheme that is suitable for a printer (CMYK in four-color printing). The preparation of print films or plates is often falsely regarded as color separation; however, transmutation from RGB to CMYK (i.e. color separation) actually occurs when the image is processed in Adobe Photoshop or when it is printed from a design program. Software that performs color separation takes into account certain printing process parameters (Photoshop settings or ICC profiles) and attempts to achieve a result as similar as possible to the original, within the bounds of what the given device is capable of producing.

 

Therefore, it is important to remember that a solution compiled for one device might not provide the same results when printed with another device. For example, huge technical problems may arise with a solution designed for coated paper when it is used to print on newspaper. It is recommended that designers carry out the main portion of picture processing in an RGB color system and to separate the image – using an ICC profile that corresponds to each specific place it might be used – in Adobe Photoshop. As an alternative, RGB pictures may be used when composing layouts in newer layout programs (Adobe Indesign CS, for example) if the user ensures that RGB- and CMYK profiles have been correctly designated and the output type is a composite PDF with CMYK- or CMYK and spot colors.

 

Despite the differences, there are also many similarities that allow a given general profile to be used in this print process and with a number of paper types. ISO standard 12647-2:2004 details European parameters for sheet-set and heatset printing; coldset printing parameters are regulated by ISO 12647-3:2004. Several organizations have carried out test printing according to these ISO standards and have completed ICC profiles that correspond comparatively well to "average European print shop" results. The most recent profile kit for sheet-set and heatset printing can be downloaded from the European Color Initiative web site at www.eci.org (ISOcoated, ISOuncoated, ISOwebcoated). Europe ISOcoated FOGRA27, which comes with Adobe CS2 software, also stems from this data. A profile suited for newspaper printing can be found from the Ifra web site at www.ifra.com (ISOnewspaper26v4).  Profiles for coated paper (Euroscale Coated v2) and uncoated paper (Euroscale Uncoated v2) included with Adobe products can also be utilized for sheet-set offset print projects.

 

It is important to keep in mind when using standard profiles that not a single print shop is obliged to follow the standard, and visible color differences may appear in a print project even when the standard is followed. If a client wishes to achieve a greater level of precision, it is necessary to use profiles specific to the given print shop and the paper type; these can typically be found on the print shop's web page. The technical committee handling print standards in Estonia may be contacted through the Association of Estonian Printing Industry (www.trykiliit.ee). 


Combined colors (spot colors)


"Corporate colors" are usually designated using PANTONE® color codes, which reference a given color-mix solution. It is important to keep in mind that a single color mix may provide significantly different results when printed on different types of paper: for example, you can compare 123 color used on coated and uncoated paper from the sample according to the PANTONE® solid coated and solid uncoated fan guides. It's wise to designate different corporate colors for different paper types, as well as for various printing methods, in order to achieve a result that is visually similar: for example, PANTONE® 115U (uncoated paper) could be an equivalent for PANTONE®123C (coated paper) when printing business cards or forms. This factor is often overlooked and the results may stray from the customer's wish, since a printer mixes colors by number and checks the result using a fan guide that corresponds to the ordered paper type.

It is also worth noting that a great number of PANTONE® spot colors are not practical for use in four-color printing, and equivalents found using a computer or a fan may not give the desired results. Furthermore, older color fan guides and software are based on print colors used in the US.

 

File naming

 

 

Each PDF may contain one or several pages, depending on the nature of the specific project and its production process. File names must include the title of the project and the page number(s). It is also recommended to include the format.

For example: noukogudenaine_007-0015.pdf, pulgatehaseVoldik_297x210mm.pdf

Given the various requirements of operating systems and FTP protocol, file names may only include numbers, letters without diacritics, underscores (_), minus signs (-) and periods (.).


Power-press printing, spot varnish and more
 

Figures necessary for post-production operations such as power-press, blind stamping and others must be contained in the PDF file using the respective SPOT color (Press or Varnish, for example) over the design, and overprint must be activated for all objects. Press-cut line thickness should be 0.4 mm and a constant dotted line is required for the blade and groove. The item's bounding box must be indicated with cut marks.

A separate file containing only the power-press figure and cut marks is mandatory in the event that the operation is executed on a program-directed device.
