drukarniaKREATYWNA Technological Guidelines for the provision of printing services by CGS Drukarnia Ltd in Mrowino near Poznań, ul. Towarowa 3

1. Print preparation Print materials should be prepared, delivered and accepted in accordance with the specification “Preparation of print materials”: http://www.cgs.pl/id/16/przygotowanie-do-druku

2. Basic quality standards The finished product should be made in accordance with the contract and the guidelines provided by the customer in compliance with all printing and bookbinding standards. Below are presented all the acceptable deviations from the ideal caused by technological limitations. Technological limitations are affected by the quality of the raw materials used for the production of the subject of the order, for which the company CGS Drukarnia Ltd is not responsible, and by technological limitations of the machines used to execute the order. 2.1 Printing. A colour pattern should be supplied for printing which will allow for the production of a print which is compatible with it. Colour patterns supplied for printing must be uniform. In a situation where proofs are supplied along with e.g. a sheet of the previous print (printing sheet without additional refinement), the customer is required to determine which of the supplied patterns is a binding one. 2.1.1 Proof. A proof delivered for printing as the binding colour pattern should be made in accordance with ISO 12647-2, each proof must be marked with a bar for measurements, the suggested control bar is UGRA/FOGRA for the purposes of the certification of the proof. If the proof does not pass the certification process, the customer will be informed about it. The proof supplied by the customer may serve as a model for printing, but it should be expected that there may be colouristic discrepancies in relation to the pattern. CGS reserves the right to make an additional proof at the expense of the customer, after informing them, when the model provided by the customer does not meet the above mentioned conditions. The following data may be included in the proof: • date of production • title of work • page number • ICC profile used for the proof • UGRA-FOGRA control bar allowing for the certification of the proof. 2.1.2 A printing sheet from a previous edition. A printing sheet from a previous edition may also serve as a model for printing, but only if it has: • control fields which make it possible to make measurements of what densities and dot growth were used for printing. • it can not be subjected to additional refinement processes (UV varnish, gloss/matt foil) • the order for which the sheet was made is not more than a year old, while the sheet itself has not been exposed to direct sunlight. • the base of the sheet supplied as a colour pattern is consistent with the printing material of the current order, it is crucial for white balance. 2.1.3 Acceptance of the print at the machine by the customer. In the case of direct acceptance at the machine by the customer, the customer is obliged to sign 5 sheets which automatically become a model for printing, if the circulation is in excess of 100,000 sheets the customer is obliged to sign 10 sheets which automatically become a model for printing. After the sheets have been signed by the customer the values are entered in Image Controle and it is used for printing. After the print is completed it is possible to generate a report of the production process for a given order. CGS reserves the right to prepare an additional proof at the customer’s expense, after informing them, when the model supplied by the customer does not meet the above mentioned conditions. 2.1.4 Printing without a colour pattern and customer acceptance. Printing will be executed using standard density or according to ISO 12647-2. The material chosen by the customer has an influence on the colouring of the print. If their white colour does not meet the standard ISO 12647-2, we reserve the right to a potential colour discrepancy. The colours of the finished product are also affected by further refinement of the type: - UV varnish

drukarniaKREATYWNA - dispersion varnish - gloss/matt foil 2.2 Methods of colour quality control of the print. CGS Drukarnia Ltd has two densitometers GretagMacbeth D19C and Image Controle Heidelberg. GretagMacbeth D19C measurement conditions: • black pad • optical densities standard E according to DIN • no UV filter • polarizing filter Image Controle – it is a device that enables printing which complies with ISO 12647-2 while maintaining three ranges of tolerance “narrow”, “medium”, “wide”. In addition, when resuming a print job which was done before it is possible to print it in compliance with the previous version, using identical parameters. Image Controle also generates reports from the printing of orders, which allows for more control over the quality of a printing job. Printing is done in a standard D50 lighting. Fluorescent lamps above the printing machines are replaced once a year. 2.2.1 Proof When printing using a proof, the compatibility of colours between the proof and the print is checked visually. It must be borne in mind that the visual assessment must be performed in a standardized D50 lighting, it is so because the print was made in such a light. 2.2.2 A print sheet from a previous edition. Evaluation of colours between a print from a previous edition and the current print is done visually. It must be borne in mind that the visual assessment must be performed in a standardized D50 lighting, it is so because the print was made in such a light. One should not take into account the differences in values in the control bar between the supplied reference sheet and the current print as the previous edition print could have been made on a different machine. Besides, it must be borne in mind that large intervals between editions will affect the change of colours on the sheet (yellowing of the substrate, weakening of colours on the sheet, comparing a “wet” sheet from the machine with an old model). 2.2.3 Acceptance of the print at the machine by the customer. Printing is done using Image Controle - after the sheets have been signed by the customer the values are entered in Image Controle and they are used for printing. After the print is completed it is possible to generate a report of the printing process. 2.2.4 Printing without a colour pattern or customer acceptance. Acceptable deviations from the model of colours in production prints for: printing by Lab parameters for particular colours, in accordance with ISO 12647-2 “Process control for the production of half-tone colour separations, proof and production prints” The standard norms of density by the classes of paper. Acceptable CIELab deltaEab deviations between: K C M Y a proof and a standard print 4 5 8 6 production prints 2 2.5 4 3 * the norm accepted in CGS: Em deltaE 1 cm. Binding which withstands the tearing of a single page with the strength above 4.5 N/cm is considered as appropriate. CGS Drukarnia does not have a PullTester, but it may commission such a test on the express request of the customer. The strength of perfect binding without staples may be examined using an organoleptic method. Binding whose folded sheets (pages) do not fall out as a result of normal opening are considered appropriate. In addition, the strength of the binding is considered appropriate if when holding one of the central pages and shaking it gently, the page holds the weight of the whole block and does not fall out. •

side gluing between the cover and the inside overlaps a standard 5 mm on each side (the second page of the cover and the first page of the inside as well as the last page of the inside and the third page of the cover), and it covers the image in the

gluing area. In the case of spreads between these pages (combined image/graphics on the pages) it is necessary to move them apart by 5 mm away from the spine (the joining of the image is then shifted by 5 mm) internal spreads should be moved apart on the side of the spine by 1.5 mm on each side it is possible that glue sticks out by 1 mm outside the crease which limits side gluing the thickness of the spine should be determined before preparing materials for the printing of the cover (it depends on the size and thickness of the material used to print the inside) due to an improper arrangement of fibres in paper, in internal folded sheets waving may occur in the spine gluing area which may hinder opening incorrect arrangement of fibres in internal folded sheets (fibres perpendicular to the spine) is often caused by the format of the work, economical layouts of pages on the printing sheet and the quality of print – CGS does not bear responsibility for this internal folded sheet should not be varnished, in particular on the spine as it will significantly weaken the strength of the perfect binding too big a difference in weight between the cover and the inside may result in unsticking of the finished product the format of the bound work and the gluing area may also influence the strength of perfect binding (album format or the spine being on the shorter side will result in a significant weakening of the strength of perfect binding). It is due to the ratio of the length of the glued side to the length of the side perpendicular to the glued side. the strength of binding is also affected by the arrangement of fibres in folded sheets and the cover

Sewn-glued binding is dedicated to bind works whose inside is printed on paper with higher weights (from 135g/m2, assuming that the thickness of the spine will not be smaller than 2mm), the expected time of use will range from a few to several months (spare parts catalogues, service manuals). In the case of sewn-glued binding the spines of folded sheets arranged one behind the other are joined together by sewing threads into a block, then in the place in which the sewing is administered glue is applied and the cover is glued. In this kind of binding no milling is required. In the case of sewn-glued binding, it must be remembered that: • side gluing between the cover and the inside overlaps a standard 5 mm on each side (the second page of the cover and the first page of the inside as well as the last page of the inside and the third page of the cover), also covers the image in the gluing area. In the case of spreads between these pages (combined image/graphics on the pages) it is necessary to move them apart by 5 mm away from the spine (the joining of the image is then shifted by 5 mm) • it is possible that glue sticks out by 1 mm outside the crease which limits side gluing and the endings of the threads used to sew the folded sheets into a block • in the middle of the bookbinding sheet threads will be visible and glue may also be seen in the places where threads go through the spine of the sheet • the thickness of the spine should be determined before preparing materials for the printing of the cover (it depends on the size and thickness of the material used to print the inside) • in the case of sewn-glued binding tearing may occur on the spine in the cutting area, it is caused by the difference in thickness between the spine and the rest of the work. 2.8. The format of the final product. The format of finished products is measured in two dimensions: • from the spine to the front side of the product – the width • from the upper side to the lower side of the product – the height The format of the final product should be compatible with the format specified by the customer. Acceptable deviations of the format relative to the order: Acceptable 1,5 mm 2.9. Rectangularity. Perpendicular edges of the product should form an angle of 90 degrees, deviation from rectangularity is measured in relation to the spine and it should never exceed 2 mm on the long side of the copy. Acceptable 2 mm 2.10 Missing copies CGS reserves the right to deviations in quantities of finished products agreed upon in the contract: Circulation Maximum deviation 50 000 - 200 000 1.0% > = 200 000 0.5%

drukarniaKREATYWNA If the customer finds that there are too few copies in the order or detects defective ones in an amount not exceeding the amount specified in the table above, a complaint will not be taken into account. Copies missing from the order detected in the printing house will be reported to the customer prior to shipment and at the same time the sum in the invoice for the work will be automatically reduced by an appropriate amount.
