Printing’s Like a 3 Ring Circus

Printing is never boring

Printing is never boring

A typical offset printing plant is like a 3 ring circus. I say that not because Barnum and Bailey was just in town, but because there are three basic workstations a job goes through before it becomes a finished product, and if you’ve ever visited a print shop you’ve seen people hurrying here and there, heard lots of odd sounds, and smelled unusual smells. Printing is not really a circus, but anyone in the graphic arts can see the similarities.

Ring No.1: Prepress

No job enters onto the press room floor without going through prepress first. Your electronic files may be perfect and prepared exactly in the manner that the printer has requested, but will still need prepress. For example, does your job have multiple pages like a booklet, or a book? Then the prepress department will have to paginate your pages. Is that confusing? After all your file was in order, probably in reader spreads, why then should it need to be paginated?

If I was sitting across your desk from you I would demonstrate what I mean by taking an 8 1/2″X11″ standard size sheet of paper and folding it in half to 8 1/2″X5 1/2″ inches. Then I would fold it in half again so it becomes 4 1/4″X5 1/2″ inches. This folded sheet of paper would represent an 8 page press signature. You can verify this by writing consecutive numbers 1 though 8 on the bottom right corners including the back. Don’t unfold it to do this, just lift each corner. It is easiest if you have the last fold on the right and the other folds at the top, this leaves the bottoms open for numbering. Now open your mock press sheet. On one side you should find the numbers 1, 4, 5, and 8. On the other side will be the numbers 2, 3, 6, and 7. You will probably also see that the numbers you wrote on the bottom right hand corners are no longer in the same place. The direction the number is in is the direction of the page. For example, page 1 and page 4 face one another, and so do 5 and 8. This seemingly unorganized alignment of pages and numbers is precisely what is needed to print the job so that it will bind as a booklet.

At this point you may think that it would be helpful to pre-paginate the files yourself. Don’t even go there. There are other complexities that come into play like the size of the press sheet, the size of your page, and the size of the press it is printing on. Trust me it is best to leave pagination to the printer.

Center Ring: The Press Room

Ah, the press room. The printing press is what it is all about. This is the place where ink hits paper.

Other than the name and the fact that they have machinery, no two press rooms are alike. Printing presses come in all sizes from small enough to almost fit in the trunk of your car to towering three story tall monstrosities, and everything in between. It is not true that if you’ve seen one press, you’ve seen them all. But, and here’s the good news–it doesn’t matter much. A cursory knowledge is all you need to be a reasonably competent buyer of printing. You don’t have to specify that the project be run on a 40″ eight unit press with a perfector and in-line aqueous coater. What you have to know is basically the dimensions of the job, the numbers of inks, the paper, what coatings if any, and bindery processes, i.e. does it fold, staple, or bind some other fashion? Then you need to shop around until you discover the printers who are best at that niche. Or even easier, contact a print broker like myself to get you to the right place.

You need to understand that I have no objection to a sales rep from a printing company serving as your source of information as long as you keep in mind that they are obligated to their employer to direct the work there. A broker on the other hand is independent and free to place your job where it fits the best. That’s why I became a broker. I hated working square pegs into round holes just because my paycheck depended on it.

Ring No.3: The Bindery

Again, binderies are as varied as much as there are printers. Commonly they will all have cutters and delivery stations. Other than that they could have folders, saddle-stitchers, perfect binders, collators, etc.

The bindery is where the paginated printed sheet turns into a booklet. The first stop is the cutter. A press sheet will often have color bars, targets, and tic marks for bleeds. You don’t want any of these things to appear on your product, so they are trimmed in the cutter.

The trimmed press sheet goes to the folder where it folds exactly the way you did in Ring No.1 except not usually by hand. The folded product looks very similar to the one you made, but one side will be a little longer.

The next step if you want a stapled booklet is to take it to the saddle-stitcher. The press signatures are stacked precisely to allow the machine to grab the longer edge. The sheet opens as it is pulled and drops onto the chain (it isn’t really a chain, but that is what it is called). If there are additional pages in your booklet there will be multiple stations filled with signatures. Each one stacking on top of the other. Once gathered they go through the stitcher. The stitcher doesn’t look like any stapler you’ve ever seen because first of all there aren’t any staples. You’ll see spools of wire like fishing line that feed into the equipment. You’ll hear a chunk sound as the wire becomes what you know as staples. The final stage is the trimmer, usually called the three knife trimmer. Until this stage your booklet still has the folds at the top, and the bindery overhang or lip on the face. Those things have got to go, so into the trimmer they roll, the blades come down and cut off the top, face, and bottom just to make it even.

Finale

The finished product is boxed, shrink wrapped, or skid packed and sent out for delivery. Is printing a career for just anyone? No. No more than just anyone joins the circus. Printing is a demanding, insane, deadline driven business. The three rings: prepress, press room, and bindery are the stages where the action takes place, but the real action, just like in a circus, happens with the people. It requires the attention of a juggler, the precision of a tight rope walker, and the humor of a clown to make it through the working day. Tomorrow it all starts over, but the show must go on!

If You Ask, Paper Info. Comes, & Comes, & Comes . . .

Sunday, March 29th, 2009

When I first began selling sheet-fed printing in the early 1980′s, my company Progressive Printing, printed an announcement flier for me. Before then I didn’t have much experience with paper other than commodity sheets used on web-offset presses. Think of magazines, catalogs, and newspapers. In the sheet-fed business a whole new world of paper opened up. I was so ignorant of paper that I didn’t understand that the paper my announcement was printed on was an expensive sheet. I didn’t know it until the office manager looked at it and said, “Wow, they must really like you because this is Cranes Crest.”

“Huh,” I said, “What is Cranes Crest?”

It turns out that Cranes Crest is made from 100% cotton fibers and is most often used on upper end letterheads and such.

Nothing more was said about my flier paper, but I realized that I had a whole lot to learn. Luckily for me a paper specifier from Zellerbach Paper Company conducted a mini-seminar in our offices. He covered paper fundamentals. His name was Mark Lander and even though he is no longer in the business I can still recall almost word-for-word some of what he taught us that day. Some of the lessons I’ve adapted and use as 60 second sermons when a customer needs to understand one aspect of paper or another.

I learned about paper because I felt I had to learn to do my job. Most people, including graphic designers find paper stocks they like and pretty much stick with them. There is nothing wrong with that approach. After all we can only hold so much information in our heads at one time. Because I took mastering of paper seriously, I found that my customers trusted my opinions and sought my advice.

If you are one who would like to know more about paper and don’t know where to go to get educated, let me give you some ideas.

  • Check the yellow pages, or call a printer to find out who your local  local paper merchant’s are.
  • Ask the paper merchant if they hold educational classes and attend if you can.
  • Be sure to get swatch books and begin building a library of paper options. If you are a frequent user of printing papers they may be willing to furnish you with a whole paper cabinet, at no charge. Ask.
  • Find out how they treat new paper introductions. Do they hold paper parties or bring mill reps around to the various buyers. Ask if you can get on the invitation list.
  • Research paper on the Internet, some specialty papers may not be carried by your local sources.
  • Many of the paper mills have websites that allow you to sign on to their news-feeds. Sign up, this will keep you ahead of the pack.

One service provided by most paper merchants that I’ve found to be particularly helpful is their willingness to create paper dummies. If you have a project with multiple pages there may be weight issues to consider. Your choice of paper could cost or save you a ton of money in postage expense. I’ve often had dummies made and taken them to the business services department of the post office to have it weighed so we would know for sure if we would pay a higher or lesser price. Often postage on a direct mail campaign will cost more than the printing and design of the pieces.

In a future blog I’ll get into paper weights and finishes, so hold on more is coming.

Black Paper & Artistic Dreams

Thursday, March 26th, 2009

First, I want to thank all of you who read my blog about the challenges of offset printing on black paper. I especially want to than those who have responded with additional  suggestions and recommendations.  Whenever there is a challenge you can expect the cleaver production people in the printing universe to find a way over, through, or around the problem. Kudos to you.

Mr. Carlo Toscano of Global Printing in California pointed out that the digital printing industry has solved the problem by laying down a base of white and then printing on top of it. I have not personally seen this done digitally, so I’ll have to take his word for it. My concern is founded on what I have experienced, and that is that opaque white inks aren’t opaque enough. The black paper is tamed some, but still allows the paper color to influence the image and makes it gray. Digital is so new on the scene and uses different technologies than offset printing, that they probably have found a way to make it work better. I’d like to see samples if anyone has them.

The downside? Digital printing is most cost effective in very small runs. They generally top out at 500 – 1,000 imprints. If you need a larger quantity digital may not be for you.

Mr. Harvey Halperin (no company name) wrote, “Lay down a double hit of opaque white then dry trap process colors onto it. This will require two print runs, to allow the opaque white time to dry. We often do this with foils, or foil stamp and print on the foils there are a few new press that do this in line.”

Mr. Halperin is quite correct. A dry trap is a technique used by printers wherein they lay down a color and allow it to dry thoroughly before printing on top of it. A single pass of opaque white, as I said before, hasn’t proven to my satisfaction to be sufficient. A double bump, or a double hit, would certainly form a better base. If the white ink is allowed to dry, you avoid the problems associated with co-mingling wet inks. Contaminated inks will turn your normal process colors to pastels, but maybe pastel is what you are trying to achieve.

The downside? Every pass through the press requires additional make-readies, and plates. This technique will give you a good result, but you’ll pay for it. His other suggestion of printing on top of a white foil stamp will also work, but again you have additional costs that come into play. The double-bump, dry-trap technique probably work out to be the most cost effective way to achieve it.

There was also a suggestion to screen print the sheet. Silk screen inks are more like paint than they are offset inks. Because by nature they are more opaque, you may not have to lay down a base of white at all. It is a suggestion worth considering depending on the quantity you want to print and how the printed piece is to be used.

My point? With very few exceptions, the mid-night brainstorms graphic designers have, are by-and-large achieveable. If the budget is sufficient,  we can find a way to make their artistic dreams come true.
