Printing Guidelines 2017 Technical Specs and Best Practices for Publication Ad sizes and deadlines • Quick file-prep checklist • Electronic ad delivery requirements • Newsprint color swatches In order to produce a high quality newspaper ad, press considerations must be addressed at each stage of ad preparation. In particular, the absorbent texture of newsprint causes significant dot gain on press. This guide includes specifications that will help compensate for press gain and variances and help you design ads that will reproduce well in The Boston Globe.

    COMMERCIAL PRINTING GUIDE a Guide to Color Reproduction and Print Quality for The

    COMMERCIAL PRINTING GUIDE A guide to color reproduction and print quality for the GENERAL INFORMATION The Jackson Hole News&Guide strongly suggests that a high-end page layout program be used for file creation. These include, but are not limited to, Quark XPress and Adobe InDesign. These programs allow vector & raster elements to be used, and each to be recognized, by the systems used, including RIPS and preflight software. Creating files completely in raster applications such as Photoshop, may result in vector elements being downsampled by one of the processes used. The Jackson Hole News&Guide, as is customarily the case with newspapers, does not have true bleed pages (Double Truck pages do use ‘gutter’ space, so an exception to this rule). The dimensions given will always be for the ‘live’ area. PDFs are the preferred file format. The preferred job option setting Press Quality. DOT GAIN/LOSS DOT GAIN The Jackson Hole News&Guide is in line with the industry standards regarding dot gain for offset printing. This is not a linear increase and may vary from 20% to 30% depending on tonal range. The important items to remember are: 1) Images will generally print darker than what you see on the monitor. 2) B/W gain will be limited to Black, while process color images gain on all 4 colors. 3) Shadow detail will generally be lost. 4) Dot gain from ‘unwanted’ colors will change the hue of a color. Unwanted colors are those colors not used to create the primary color wanted; for example, cyan is the unwanted color in red, magenta is the unwanted color in yellow, etc.

The 2-day workshop and 1 interim day of lectures cover the production of inks from historic recipes; historic drawing and writing techniques; identification, examination and classification of deterioration; and the execution of treatment options, including the use of calcium phytate solution. The interim day of lectures will feature local and international conservators' research into the history and treatment of works with iron gall ink. The course represents the first time iron gall ink has been the primary focus of an international gathering in the United States. Registration deadline for the full course is July 1 or until the course is filled with qualified applicants; for the interim day of lectures only, participants have until August 29 to register.

    Ask Gamblin - The Color Episode Antrese: Robert and Scott, thank you so much for being on the show. Robert Gamblin: It's great to be here. Thanks for having us back, Antrese. Scott Gellatly: Great to be here. Absolutely. Antrese: I'm super excited to have you guys on to answer these questions about color. And our first one is from James, and James has heard that modern oil paints actually have too much pigment as compared to traditional historic pigments. What are your thoughts on this? Robert Gamblin: Antrese, I love this question. I'm really glad that James brought it up. It gives us a chance at the beginning of this conversation to sort of put everything into kind of a historical perspective. It's true. The formula of today's colors have more pigment in them than at any time in the history of oil painting. That's true. Now the formula for the colors of today and the colors from historical periods. Both of those reflect what is expected of them. Now 200 years ago, or more, color was made and used in very close proximity. Perhaps it was made and used in the same room. The color was made to the texture that it was going to be used at. Robert Gamblin: So there was no need to make that paint any stiffer than the, very smooth painting that was done at that time paints were paintings were generally thinner than they are today. Multiple layers, those layers with very thin. And so the paint was made exactly to how the painter was going was going to use them.

Washing is most efficient at removing the smallest particles of ink. The optimum size range for the different techniques is illustrated in Figure 1.1. Figure 1.1. Optimum particle-size range for the various techniques in ink separation (after Shrinath et. al. [9]) 1.2.2.1. Washing and flotation In contrast to screening and cleaning, which are merely physical separation processes, washing and flotation operations require chemicals to help them perform efficiently. Although washing and flotation are both carried out to remove ink particles, their operating principles are entirely different. Washing systems are most efficient at removing ink particles smaller than 104m, while flotation works best at removing particles in the 10-1004m range. Furthermore, the washing process requires ink particles to remain in the aqueous phase so that they can be removed along with the Deinking of Newsprint: An Overview DEINKING OF NEWSPRINT BY FLOTATION METHOD Bimo Ariadi, B.Sc.

CHANGES IN PRINT PAPER DURING THE 19TH CENTURY AJ Valente, ([email protected]), President, Paper Antiquities When the first paper mill in America, the Rittenhouse Mill, was built, Western European nations and city-states had been making paper from linen rags for nearly five hundred years. In a poem written about the Rittenhouse Mill in 1696 by John Holme it is said, “Kind friend, when they old shift is rent, Let it to the paper mill be sent.” Today we look back and can’t remember a time when paper wasn’t made from wood-pulp. Seems that somewhere along the way everything changed, and in that respect the 19th Century holds a unique place in history. The basic kinds of paper made during the 1800s were rag, straw, manila, and wood pulp.
