Printing and Production Techniques

Blind embossing creates a raised or recessed effect by applying pressure to paper or board. Metallic foil stamping transfers a decorative film. They can be combined on some projects, but they are different techniques. How blind embossing works Tools and pressure reshape the paper to produce a raised or debossed area. The result depends on

A very fine pattern, a cut-out invitation or a cardboard piece with complex geometry may require something other than guillotine cutting. Paper laser cutting uses concentrated energy to cut or mark the material along a programmed path. It can be useful for prototypes and highly detailed designs, but it is not suitable for every paper,

A printed book cover size is not defined by the dimensions of one page alone. For a flat paperback cover, add the back cover, spine width and front cover, plus the bleed required by the printer. An error of a few millimetres can displace titles or leave the spine off centre. For a flat paperback

Legal deposit for a book in Spain serves to preserve publications issued in the country. It is governed by Law 23/2011, as amended by Law 8/2022, and is not the same as obtaining an ISBN. Who must apply for the number? For a work published in a tangible format, the publisher is normally responsible. The

An ISBN commercially identifies an edition of a book and helps manage its distribution. If you are publishing a work in Spain, you may need one to work with bookshops or platforms, although the Spanish ISBN Agency confirms that it is not a general legal requirement for publishing a book. An ISBN does not protect

When someone requests “silk” or “satin” paper for a magazine or catalogue, they may be imagining a very glossy stock, a smooth surface with moderate sheen or even photographic paper. The terminology varies between markets and does not always identify the same product. In commercial printing, silk-coated paper normally describes a smooth surface with an

Coated paper is one of the most common stocks for magazines, catalogues and brochures containing photographs. Its treated surface changes how it accepts ink, and it is available in several finishes. The important point is not to choose it by habit, but to understand what it offers compared with uncoated paper and which finish suits

A4, A5, A3 or A6? Choosing a printed size seems straightforward until you need to prepare a folded brochure, magazine or poster that must fit a display. The format affects the design, readability, folding, paper and production method. The best-known printing paper sizes belong to the A series defined by ISO 216. B sizes, C

When a printer suggests Offset paper, this does not necessarily mean that the job will be produced on an offset press. The term describes a family of uncoated papers with a natural surface, commonly used for books, notebooks, forms and corporate stationery. The choice matters: a novel needs comfortable reading, a photographic catalogue may benefit

Spot varnish adds a finish to selected areas of a printed piece. It can highlight a logo, headline or graphic detail, particularly on business cards, book covers and certain Packaging products. However, combining spot varnish with roll-up banners requires more care than promotional claims often suggest: retractable graphics bend, and not every varnish or substrate

Format, quantity, paper, inks and finishing all affect the cost of a print job. Before comparing prices, check that both quotations describe the same product. To choose the right option, confirm the intended use, material and finished dimensions of the product. Digital or Offset printing? Either process may be suitable depending on the volume and

A photograph printed in a magazine appears to contain continuous changes in colour. Under a magnifying glass, however, it is made up of many tiny dots. The way these dots are arranged is called halftone screening, and it is fundamental to reproducing highlights, shadows and intermediate tones in print. Several screening systems are used in

A4 is widely used for office documents, manuals, brochures and publications. Its physical dimensions do not depend on the software used: A4 paper measures 210 × 297 mm. What changes is the number of pixels when an image is created at a specific resolution. For print production, it is important to distinguish between trim size,

A shop window may need advertising without completely blocking the view outside. Perforated window vinyl has tiny holes that allow some light through and provide a degree of visibility through the material. The effect is not automatic and does not work in exactly the same way by day and night: it depends on the lighting

An image may look sharp on screen and print blurred in a brochure. It may also create an enormous file without adding visible print quality. What matters is the effective resolution at final size, not an isolated number in the image properties. When preparing images for Offset printing, distinguish source pixels, the dots produced by

If a coloured background reaches the edge of a card or brochure, designing it only up to the trim line is not enough. A slight movement during cutting could leave a white strip. This is why artwork includes bleed for printing. Bleed extends images and backgrounds beyond the finished size. It must not be confused
