My teacher asked us to do a research on one thing we like, it could be anything, but I did not have any idea what I should write, then I decided what I saw next I would research it, to my surprise, the first thing came to mind is posterprinting, which was used for advertising a movie, which had not been released yet, since I had no better choice, I might as well do some research on posterprints. Posters can be used as an advertisement, some posters are designed by artists, so they are more attracting, but the business characteristics are still very obvious. You can say posters can be posted on the wall or even shown in the media, so the photographic prints posters have become more abundant than ever before. At first, when the poster printing software has not been invented, people painted posters with their hands, so the poster can be finished with more than several days, if the poster is pretty complicated, it may need labor work of more than one month. You could not find a single poster print shop in the street at that time, but now, things have completely changed. There are many kinds of posters, the poster I saw on the road when I walked from school to home is the movie posters prints, which was used very widely in modern days, when a director is going to release a movie, he would do some promotional work to make him movie know, so the best poster prints will reveal to you the basic information about the movie, the release date of the movie, the main casts of characters, and some very fascinating act in the movie and so on. advertising poster printing is the main application of poster screen printing,unlike the old times, when posters were made by human labor, today, with the poster printing program installed in the computer, there are some professional people who will click some keyboard, then the machines can start print out posters. You may wonder how much is one poster? Is the cost of poster printing high or low? Well, I have to say it depends, if you are in need of the movie poster prints, the cost may be a little higher, since the poster has to be an art piece itself, from the color of the whole picture, the characters, to the format of the entire picture, the poster should be exquisitely designed without any flaws, so make poster prints will require great work of professional people, these poster are also called as “screen printing posters”, which can be used in different occasions, and the whole printing process is rather simple and efficient. This is available, of course, with the help of poster print software. These kinds of photographic poster prints can be posted on the walls or in the beach or some other places. So we can safely say that posters have become one part of our lives. Then I remembered I forgot to include another type of poster printing, that is motivational posters prints, I guess many people would feel so puzzled, these are the kinds that promote the inspirational content, for example, the poster of promoting establish environmentally friendly city, or the poster for the purpose of expanding the transfer love and warmth to other people, these are also very important part of posters printing. There is not only poster printing shop existing in the streets, there also appear online poster maker, which can also help develop the poster printing business improve faster. Besides poster printing, the whole printing business will prosper, including paper;paperboard printing.
