  1. Preparing images for stochastic screening

    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...
  2. Fifth Color Channel

    What is ink rotation? Can you explain about ink rotation? I have no idea about it. I am planning to use a custom color 5 th channel. There is a company that does specialty inks. But I don't know how much ink I will need to order. I am printing 1000 books. The book is going to be 300 pages, but...
  3. Fifth Color Channel

    No I haven't tried any testing with the PMS. By the way what does PMS stand for? Sorry for the silly question but I know it is referring to the 5th solid color. I need to find the right amount of ink and a company who is willing to do the test. Nowadays most companies are reluctant to spend...
  4. Fifth Color Channel

    Thanks for input I understand what you mean. And I think some of the Pantone solid colors will work fine for the most part of the blue color, but there are some areas which go darker than the actual solid color's 100% value. Those parts definitely need a little more additional color from CMYK...
  5. Fifth Color Channel

    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...
  6. How to print deep blue

    I think proslack was right! After meditating about it for some time, I concluded that we must try the Hexachrome printing. So I started looking for some companies that does this. If I can find a good hexachrome printing company in China, it would be a lot closer to my home. But if it is not...
  7. Question about book sizes

    Hi again after such a long time. I started to look for Hexachrome printing factories to print my book. Do you know any such printing company in China? There are number of Hexachrome printing factories in the USA, but it is very far and also I have designed my book according to Chinese paper...
  8. Question about book sizes

    Dimension reconfirmation Thanks for the reply. I will ask the Koreans about the book size. But before I do so, I want to reconfirm the book size again. On one entry you wrote 285x280mm was the good size, and on another entry you wrote it was 280x285mm. So I want to know exactly what the Height...
  9. Question about book sizes

    question from szjhy Recently I was informed that Korean printing companies use 220x315mm size as their standard book size. From your previous reply, I guess that this size is probably made out of the 965x635mm printing sheet. >>>>>You mentioned that 985x635 size is used for oversea's...
  10. Creating a Spot Color Channel in Photoshop

    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...
  11. How to print deep blue

    I saw Pantone Process Guide Coated, and that formula is there. But it doesn't look like the artist's color. And there many other blue shades and none looks like the pure blue of the artist's color. If you take a look at the paint straight from a tube of French ultramarine or Cobalt Blue Deep and...
  12. Question about book sizes

    Chinese printing Thank you very much for your reply, szjhy. That was very informative. Now I have a little better understanding of book sizes. It seems like you divide the height in three and divide the width in two for most books. For example, 889:3 and 596:2. Am I right? I want to ask...
  13. Question about book sizes

    Question from Chinese friend szjhy Thank you for writing a reply to my question. I have a Chinese book named “Illustrated Dictionary of Qing Dynasty Court Costumes”. And this book’s trimmed size was 285x285mm, so it was very close to your words. I would like to ask some more questions regarding...
  14. Question about book sizes

    Book specifications Thanks to Meny, I haven't set the book size at the moment, but working on it. I felt like I didn't have enough knowledge about the price differences according to the size of the book. But I will give you the numbers what I have in mind for now. 1. Wanted book...
  15. Question about book sizes

    I have the basic understanding. From one sheet of standard printing sheet, you can make 16 pages of A4 size. So if it is a little bigger you could make 12 pages out of one sheet. And I did measure the page size and made the calculations. But the manager insists that they will only calculate it...
  16. Question about book sizes

    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...
  17. How to print deep blue

    Thanks for answering my question. But I have another question from you. The Blue colors in the paintings are not made of solid application of one color, but the blues have very delicate nuances in it like translucent watercolors. However the blue is a lot more saturated in overall strength than...

    Gloss vs Coated paper What is the difference between Gloss and Coated papers? Aren't they the same thing? If they are different, which is better in rendering colors? Thanks.
  19. Advice on printing watercolor art

    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...
