Parameters of supplied documents
We prefer to work with PDF files version 1.3, but it is possible to supply PS files, resp. PRN.
We also work with open formats such as QXD, FH9, AI, TIFF, EPS, INDD (IDML) and CDR. If you supply data in any of these formats, contact us for program version specifications. These files will be converted to PDF by us and sent back for proofreading. At the same time, the time required to convert the format will be charged.
Open documents, such as files saved from Microsoft® Word, Microsoft® Excel, Microsoft® PowerPoint, OpenOffice, will only be accepted by prior arrangement and must contain linked images and fonts.
You can send files by e-mail, upload to FTP (always send an e-mail or call that there is new data on FTP , only after the upload of files is finished), send using third-party services (uschovna.cz, etc.), bring on a flash drive or CD.
Color
The correct color of print data is a basic condition for the preparation of documents. When delivering substrates with poor colors or other color spaces, the output colors may change dramatically (in which case bad printing cannot be complained about). Please always observe the following points:
All vector and bitmap objects must always be in CMYK , grayscale, or spot colors.
If they are in the RGB or other space, it is necessary to take into account the color otherness (degradation) after their conversion into print separations - in this case, we will notify the customer and request a redesign or. we offer adjustment (charged DTP more work). Our printer is not responsible for color shifts.
Direct colors must be named correctly (preferably selected from the Pantone color swatch - eg Pantone 133 C).
It is undesirable to call a color such as "blue", "color", "silver", HKS or Pantone without a number.
If you do not know the relevant Pantone color, we can convert it for you according to the swatches - however, the accuracy of the color after conversion by estimation cannot be guaranteed. In the same way we can convert colors from Pantone to CMYK (charged DTP more work)
Black color
Areas - When using larger areas filled with black for CMYK offset printing, do not define black as CMYK: 100/100/100/100, but set the following values to achieve ideal saturation: COMPOSITE BLACK CMYK: 64/55/53/100
text - text printed in black must be created only from this black and not from 100% of all other colors. When printing black, only black is printed, which is nice and sharp. However, if we have text of all colors, they will overlap and the text may appear blurry or unsightly shaded at first glance. Black must be only black and must not contain any other added colors, otherwise the colors will be applied on top of each other (registration).
Documents must not contain ICC profiles (CAUTION, the insertion of an ICC profile is automatically performed by most applications when saving the document).
Dimensions
Specify the size of the pure format in the order
If the file contains more than one page, each must be uniquely marked with a number that determines its location during disposal or subsequent processing - if there is no marking, a mock-up must be supplied (black and white is sufficient).
Files for printing must be unclaimed, ie each page of the document contains exactly one business card, leaflet, poster or page.
The print data must be prepared in a size of 1: 1 for the final product, or in a proportional scale. Then it is necessary to supply the exact percentage of reduction or enlargement (eg from A4 to A5). Documents delivered disproportionately to the final print will be returned to the contracting authority as unusable.
For booklets, store all the inside pages in a logical order in a single file, including the blanks .
Fall and marks
Each page in the print document must contain a bleed , that is, an overlap of objects that touch the edges of the plain document size, at least 3 mm on each side that is affected. If the supplied file contains cutting marks, it must accurately indicate the clear format of the page, must be offset by at least 3 mm from the clear format and must not interfere with the clear format.
Registration or descriptive marks do not need to be inserted.
If the page is non-dropped, keep the total size of the document equal to its clear format.
If the resulting product is creased or folded, each such page in the document must also be marked with big or bend marks. Such a mark shall be indicated by a dashed line and shall be at least 3 mm from the clear format.
In the case of a product which is subsequently cut out, a drawing for the stamp must be part of the documents supplied. It can be supplied as a separate file or as one of the pages of a print document and must have the same dimensions as the print document. If it is part of a graphic, it must be composed of spot color that will not be printed and must not be set to overprint.
Distinction
Make sure that the objects are resolution correctly.
CMYK and B&W images in the supplied files must have a final resolution of at least 300 DPI. Bitmaps must have a final resolution of at least 600 DPI, and grayscale anti-aliasing must not be enabled in PDF format.
For feathers, have 1200 dpi.
Higher values do not improve the quality, they only unnecessarily increase the size of the file.
Observe the following rules when using compression: JPEG compression must be of the highest quality, preferably maximum (JPEG is lossy compression - using it reduces the quality and color of your data)
Bitmap compression must be none, or CCIT Group 4; LZW file compression is enabled.
Do not use OPI commands (save images only as a low-resolution replacement).
Fonts
Saving the file to always put all used fonts ( fonts ), including subsets - check the Embed All Fonts and Subset embedded fonts.
In PDF, Postscript and EPS documents, fonts do not have to be converted to curves, but in other formats.
We recommend having fonts smaller than 10 points in only one color.
Fonts from 10 to 24 points in a maximum of two colors.
All four colors form fonts larger than 24 points.
Prepress check
Raster data control is available to the customer before printing.
Upon request, we will send them to the customer's email address via a preview in PDF or JPEG format.
Therefore, if the customer insists on the exact color of the printed matter, it is necessary to personally check it at the beginning of printing.
Raster lineature and rotation of separation angles
The device we use allows us to create rasters with a density of up to 200 lpi with a coverage range from 1% to 99%.
This means that sharp images and more elaborate details can be achieved.
If the customer does not determine the density himself, the operator of the device decides based on his own assessment of the image, type of paper, etc.
By default, we choose 150, resp. 175 lpi with the shape of a raster point of the Euclidean type.
For printed materials where pink (skin), red or orange color is present to a greater extent, we use the following rotation of separation angles:
Cyan 105 °, Magenta 45 °, Yellow 0 ° and Black 165 °
In other cases we choose the standard: Cyan 105 °, Mag. 165 °, Yellow 0 ° and Black 45 °.
If you have your own idea, you need to point it out in the order.
