PDF to Bitmap V2.13

Issue

I want to rip and print PDF files in real-time with the Kyocera integrated into the GT controller, I want to print odd pages with inkjet 1 and even pages with inkjet 2. How do I do that?

You need 1 pdf file that contains what you want to print Front and Back with the Kyocera, you can later select which inkjet will print the odd or even pages. A flat file (txt) is made from the PDF file, it contains the page number. However, if you have more match-keys you want to control with readers, you have to deliver a file.txt with those keys you want to match in real-time. In any case, remember to add a 1D barcode with the page number on the side that is going to be cut, this page number is read by 2 barcode readers after the 2 inkjets to make sure that front and back are in sync

 

V2.13 loads 16 records in advance, good for fast webs. V2.13 needs a license per server.

 

Place the PDF files you want to convert in the server1 in d:\pdf (this is then mapped as M:\ in both the controller and the inkjet) and make a directory d:\pdf\temp. M = \\Server1\D\pdf
Place the PDF files you want to convert in the server2 in d:\pdf (this is then mapped as N:\ in both the controller and the inkjet) and make a directory d:\pdf\temp.

 

Architecture for 1 page from and 1 page back, 2 servers

1 GB LAN, make sure the dedicated switch can do 1 GB, lots of data. CAT6

Example: I am using my PC (Markus-Win7-0) as server 1. I can see that pdf is shared.

If it is not shared, go to folder and share it.

Go to Kyocera and share the server above as M:/
Go to Controller share server above as M:/

PDF2BMP program

First you need at least 2 powerful servers (i7 or more) where you want to install the program PDF2BMP. This program converts PDF pages into bitmap pages in real-time on commands received from the standard GT controller.

If you want to check how many bitmaps per minute your server can crunch, make a conversion trial per push button. No need to split the bitmap.

See elapsed time, here 55 seconds for 100 pages or 109 pages per minute. Allow for some slack when running, say 70% or around 76 pages per minute per server.

This is on my laptop. Servers should do 3-10 times faster. Also, remember that you can daisy chain servers.

Front/Back Option

First you need at least 2 powerful servers (i7 or more) where you want to install the program PDF2BMP. This program converts PDF pages into bitmap pages in real-time on commands received from the standard GT

Start of PDF2BMP program

Add startup-Pdf2Bmp.exe to start of server

Explanation

Easy, the GT controller tells PDF2BMP at start, to prepare the first 64 pages. Then more as you print. You can change that to 32 by entering in d:/editorgt/user/system/arguments.txt:
inkjet0 -bufsize 32

 

Settings in Controller

Below the regular job setting for an inkjet

The configuration is more interesting, here you can select in head settings and select the PDF file in M:/ Number of heads or head count

The resolution in transport direction: make this as low as possible to gain speed, use less ink

The drop size: make this as low as possible to save on ink
Slide position

You can select the file in the mapped folder M:/ of the server (the GT controller and the Kyocera inkjet must be mapped as M:/ to the location in the server where the PDF files are), then select the file in a regular file dialog

Make sure you have license activated

And you can operate the inkjet from the controller: purge, park, down, etc.

The inkjet needs to be in Data source TCP/IP

If you want to know how much ink is needed for 1 page or 1,000 pages, go to the layout, select a typical bitmap in M:/, here BMP-024.bmp, select the drop size and you will see the ink consumption

Matching (Important)

It is very important in any production environment, to implement quality control procedures. One of the most effective is to add a camera to control that the inkjet is printing right and in the sequence intended. Below you see a reader after the inkjet, even a gate to divert or mark bad products.

WARNING: if you combine different inkjets, for example a Raptor to print from PDF and a GT-Jet 64 to print a barcode, you must add readers and do matching. That is the only way to guarantee that the Raptor and the GT-Jet 64 do not go out-of-step because the production speed is so fast that checking it by eye is not possible !

At the very least, you should check that everything is in step every 1,000 products by introducing a quality record that you keep for archiving.

 

In the data file, you need to select the match-key. Usually the page number.

If printing front and back, you will need 2 readers, one to read the front page number and one to read the back page number.

Please refer to the GT controller manual for more information on matching !

 

In both readers, compare the reading result to the defined match-key
