Digital presses require the grain to run perpendicular to the feed direction in order to feed properly and make the sharp turns typically found in a digital press. Apr 8, 2012 | 2 min read. Using grammage simplifies data entry and avoids errors due to incorrect basis weight selection for the numeric weight value. This action and movement causes the fibres to interlace and develop a predominant alignment along the direction of movement. For example, if you scale a 72‑ppi image to 50% in the Print dialog box, the image will print at 144 ppi; however, the document size settings in the Image Size dialog box will not change. Coatings can be heavier than paper fibre so coated paper can have a smaller caliper than the same weight of an uncoated counterpart. Search for: 6.5 Paper Basics. Chapter 6. Basics of Print Production, 2nd Edition It may, however, require one to do a conversion calculation if only basis weight is provided. The bend running in the direction offering the least resistance is the grain direction. with Claudia McCue. Paper weight is one of the key characteristics that affect many parameters on the digital press, including how much vacuum strength is used for feeding, how much charge is required to transfer toner to paper, and how much heat is required to maintain a consistent fusing temperature to bond toner to the paper, among others. Happy New Year& By WhatTheyThink Published: January 14, 2002. ... InDesign Layout Basics. CMYK refers to the four ink colours used for most printing: Cyan, Magenta, Yellow and Black (or Key). Free shipping for many products! This is measured on a scale from 1 to 100, where 100 is completely opaque. This is due to the addition of fluorescent whitening agents (FWAs), which return additional blue light when exposed to UV light. Papers with uniform formation accept inks and toners more evenly, have reduced print mottling, and enhance clarity. An image which is viewed on a computer screen is in RGB. Whiteness measures the reflective properties of the paper across the entire visible spectrum of light (defined by CIE). Paper is made most commonly from wood fibre. Basis weight is the weight of 500 sheets of paper at a specific size, known as the ‘parent’ sheet size, which varies based on the historical use of the specific paper. Think about it: at the end of an exceptionally long day of work, do you feel compelled to get on your computer and read articles online or cozy up on your couch with a book? Brightness and whiteness define the optical properties of paper and differ mainly in how they are measured. Four-Color Process Printing. Hello Select your address Books Hello, Sign in. This can be very confusing as a cut sheet of letter (8.5″ x 11″), 80# text, is much thinner than the same size of 80# cover. In other words, it defines how white the paper is. Certain vibrant blues. Today, many papers also have some percentage of recycled fibre as well as fillers and other additives. Today, many papers also have some percentage of recycled fibre as well as fillers and other additives. It is important to understand that the final product will look slightly different when printed digitally vs. offset, as well as from printer to printer. The purpose of this project was to create a short but comprehensive guide to print production that could be shown to beginner designers or clients. Grammage is simply how many grams per square metre paper weighs. Entering the wrong values for the paper weight can cause paper misfeeds, poor image quality, or toner not adhering to the paper. Toner used in digital printing bonds to the surface of the paper and does not penetrate. Short grain refers to fibres running parallel to the short dimension of the sheet, and, conversely, long grain refers to fibres running parallel to the long dimension of the sheet. The amount of coating and calendaring produces different finishes and gloss appearance. The coating fills in the spaces between the fibres on the paper’s surface, resulting in a smoother finish. Cover basis weight is based on a 20″ x 26″ parent sheet. Welcome to this course, all about print production fundamentals. Examples of on-machine finishes are smooth, vellum, laid and felt. Scaling an image in the Print dialog box changes the size and resolution of the printed image only. Mary Hardesty has 30 years experience in the graphic arts industry, with experience in all areas of print production from building the budget to getting it delivered. Paper is made most commonly from wood fibre. The second edition of The Basics of Print Production examines all of those important decisions—from concept to delivery—and provides the reader with practical tips, guidelines, and knowledge about each step in the printing process, including: Developing preliminary and final specifications for a print project Formation refers to the distribution of fibres, fillers, and additives in paper and how evenly they come together. The same is true for whiteness, as papers with higher blue reflectance levels tend to have higher whiteness levels. To understand this better, let’s examine two different basis weights. It is important when conceiving of a new design that the entire workflow through to production is taken into consideration. Such fine prints, as they are known It’s important to understand some basic attributes of paper as they all have a direct impact on imaging processes and results. Print Production: Prepress and Press Checks. Cast coated paper has a very high gloss finish on the front side and is uncoated and rough on the back. On-machine finishes are achieved by the application of a pattern onto the paper by a marking roller while it is still wet. Book Description: This textbook -- written by a group of select experts with a focus on different aspects of the design process, from creation to production -- addresses the many steps of creating and then producing physical, printed, or other imaged products that people interact with on a daily basis. No other factors are represented by this designation. - Hi, I'm Claudia McCue. Opacity can be increased with fillers, pigments, or even coatings. In strict terms, opacity is the degree to which light is prevented from travelling through a paper. This predominant alignment of the fibres is called grain direction. Blueprints transform ideas into products and communicate information between engineering and manufacturing. The following conversion factors can be used to do these calculations. Read reviews from world’s largest community for readers. In North America, the basis weight is more common. When folding is required, folds that run parallel to the grain will be smooth and sharp while folds that run across the grain will be ragged, and the fibres on the top of the sheet may pull apart. Find many great new & used options and get the best deals for Basics of Print Production by Mary Hardesty (2002, Spiral) at the best online prices at eBay! When talking about substrates used in printing, paper is usually what comes to mind. In most parts of the world, paper whiteness measurement is used; however, in North America, most use brightness measurement instead. Imaging. refers to the distribution of fibres, fillers, and additives in paper and how evenly they come together. Account & Lists Account Returns & Orders. Cast coated paper holds ink well, but the toner used in digital printing may not adhere to it. In general, a thicker paper, coloured paper, or coated paper is more opaque than its counterparts. In the paper manufacturing process, a slurry of fibre travels over a high-speed mesh conveyor belt that is oscillating side to side. The caliper can vary depending on the coatings or finish. Printing is a process for mass reproducing text and images using a master form or template. 2h 38m Intermediate. Apply to Print Manager, Production Lead, Production Supervisor and more! As noted previously, a fold that runs parallel to the grain will be smooth and sharp while a fold that runs across the grain will be ragged. This is not true. When you hold a sheet up to a strong light source and look through it, the mix of dark and light areas are the result of formation. 5,951 The Basics of Print Production $25,000 jobs available on Indeed.com.
