Dear Friends, What is the Best quality ink brand for printing High-end art catalogs? I have been using inks from a Japanese company, Megami Inks. To be a little more specific: The company had a nice spot Violet ink in the past, that created a nice saturated Blue when combined with Cyan base...

What causes moire on printed images? The effect is not in the digital images, so they are definitely the result of the press. They are on some (not all) pages with grayish neutral backgrounds. I am suspecting the lines are caused by the screen angles. Although they are very fine lines at around...

Hi Printers, Does the CMYK color bars on the sheet edge show the color layout order? Which color was first and which was last? I always thought the layout order was 1st Cyan, 2nd Magenta, 3rd Yellow, 4th Black. But seems like it is not the case. I am using an additional Violet spot color...

We are having an overseas company make a print on porcelain plates. As I understand, they use a halftone screen printing technique for this, similar to CMYK book printing. Although I don’t know much about plate printing and what type of printing it is, I can see some moiré problems on the print...

I am designing a catalog for 889 x 596 mm paper and have to consider how large and how many pages I could make out of this sheet size. I want to know the width of the printer marks. And which sides these marks are put on. So that I can calculate the trim off part including the bleed. If you...

I design books and catalogs. I have a question about preparing images for press. If I prepare my file for a book on Indesign and submit it to the printer, does it go through any pixel based program (such as PDF or Photoshop) at the print shop? Or do they convert the pages directly to printing...

I am printing an art book with spot colors. Yesterday we started the printing, but there was a problem with the spot colors. The Blue areas in the artwork use Spot color + Cyan(60-80%) + Black(3-10%). The application of the spot color is not flat or 100% solid, but it is continuous tone...

I was trying to find a right ink for my custom spot color. I saw this very saturated blue ink in one printing supply shop the other day. And the shopkeeper told me that the code for this blue was 453. Today I saw the same ink in a local printing company and the supervisor also said that the code...

Hi, I am designing a book for an artist and thinking to print it with stochastic screening technology. But I am wondering how I need to prepare my images. Previously I worked only with printers who use the standard screen. So I prepared my images with 300 DPI resolution with some sharpening...

I am designing a book for an artist who uses very strong blue colors. I know that it is hard to tell the visual effect of the color from the small screen image. But when you see the original art and the printed reproduction on hand, you will see the difference. Printing the blue color with CMYK...

Can anyone teach me how to make a Spot Color Channel on Photoshop? I am using this image as an example. The blue color in the background needs to be printed mostly with a spot color that is close to the original painting color (ex: Pantone Blue 072C) . But the CMYK color still should be present...

I am designing a book for an artist. It will be quite a good size of a book since he has many works done in his career time. The artist wants a little bigger size than the standard A4 or American letter size. I went to one of the best printing factory in my town and asked the prices. The...

I am a young designer with little experience in book publishing. Currently I am working on a catalog of an artist. It consists of oil paintings and water colors. I took the photos myself. But preparing the CMYK images for watercolors is a bit tricky for me. There are many watercolors with very...

Hello guys, I want to create duotone (or tritone) images for offset printing. I am not going to use special inks for these. I will just create duotone image from the photoshop Duotone setting and choose Black for the first ink and Yellow for the second. My common sense suggests that this way...

Hello Printers, I am not a printer nor in printing industry, but I am an inexperienced graphic designer. I need an advise on how to print a very deep blue color on offset printing. I am doing a catalog for an artist who uses this deep cobalt blue color. His technique of applying the color is...
