	format of advertisement material

	We only accept advertisements in electronic form. Please do not send plates, because we are unable to perform manual installation in the printing house. We prefer CD-R discs (ISO9660 format). Files may also be sent to our FTP account (ftp.ct.com.pl), but we ask you to arrange it by phone with the advertisement production department beforehand. A printout (black-and-white or color), preferably 1:1 or with JPG preview should be attached to each advertisement. Color proofs may also be attached.

	file format

	We work on PC computers, so receiving diskettes or CD-R's in the Mac format is problematic for us (e.g. advertisements prepared in QuarkXPress on a Mac with embedded Mac fonts etc. is virtually unusable for us due to Mac fonts...).

	favoured file format EPS

	All texts should be converted to curves before export. The file should include a low-resolution or medium-resolution preview (PC). Whenever there is a choice between ASCII/binary save option, choose ASCII. Photos and other graphic elements should be explicitly embedded in the file. We do not accept multi-page EPS files. The color definition of the file cannot be other than CMYK. The files cannot include alpha channels (masks), clipping paths or additional layers and floaters. Black-and-white photos must be saved as single-channel (BW or grayscale). In the case of color photos, please use the settings provided in the CMYK Setup in Adobe Photoshop. Photo resolution 300 dpi. CMYK Setup settings in Adobe PhotoShop appropriate for chalk-overlay paper This will result in the best color reproduction on the cover. We recommend checking the complete project (EPS) using appropriate RIP software (e.g. Adobe Distiller + Adobe Reader).

	print properties

	General print parameters are similar to printing on a sheet printer (on chalk-overlay paper). Each color is printed from a different form cylinder. Thus, shifts between the machine's four cylinders are possible. The paper's dimensional stability is quite high; however, under the influence of water, it stretches in length and width depending on the direction of printing. When printing a full color advertisement, the paper takes up four times more water than in the case of black-and-white printing thus, the paper stretching effect increases. The installation of printing forms also involves an error factor. When these properties sum up, the colors printed in the newspaper are shifted. Thus, please avoid small white text <6pt. on a four-color background (in Photoshop, black consists of CMYK, not only K unless this setting is changed...).

	full-page advertisement format modules: EAP, ECH, ECIII, ECIV

	Cover format is 210mm x 297mm. In the case of preparing a bleed advertisement, it should be large enough to avoid white margins after it is clipped to fit the format. The assumed bleed size should be 5mm from top and bottom and 5mm from left or right. The total dimensions of a full-page advertisement with bleed are 220mm x 307mm. If you have any questions or doubts, please contact our advertisement production department.
