What does the MTBF or MTTF specification given by manufacturers mean?

Often you will find a Mean Time between Failure (MTBF) specification given by manufacturers on their printhead or print engine. So what does MTBF mean?
Mean time between failures (MTBF) is the mean (average) time between failures of a system, and is often considered the "useful life" of the device i.e. not including 'infant mortality' or 'end of life' if the device is not repairable. Calculations of MTBF assume that a system is "renewed", i.e. fixed, after each failure, and then returned to serv… Continue

Capital Equipment Justification: Key Tax Issues

The justification for purchase of capital equipment goes way beyond simple payback numbers in many companies today. While "Payback" is a good rule of thumb, the Return On Investment (ROI) calculations used in financial departments uses other internal factors to help determine the viability of the project and the ultimate justification for equipment acquisition. One of those factors is the current and future equipment book values over the ROI period based upon tax code and depreciation schedules.… Continue

The importance of using the right scanner when comparing label barcodes vs. inkjet barcodes

When verifying an inkjet bar code printed directly on corrugated cartons, the ANSI specs call for the use of a 20mil aperture lens. Many label verifiers are either a 6 or 7 mil aperture and are overly critical of the natural defects in the corrugated board. ANSI specs call for the 20mil pen. It is less aggressive and does not pick up the corrugate imperfections as does the more aggressive label verifier.

Direct bar code printing on corrugated boxes has been an accepted standard for 15 ye… Continue

ITF (I 2 of 5) barcode magnifications

Just posting this to share some light about ITF barcode magnifications.
Base on my research the following are the various magnifications for ITF barcode. This will be helpful when we want to compare a standard ink usage across different competitive products printing for example a standard 62.5% ITF barcode.

70%
Overall Height 1.260"
Overall Length 4.314"

62.5%
Overall Height 0.880"
Overall Length 3.627"

100%
Overall Height 1.25" ,
Overall Length 6"

History of Walmart and RFID

Heres the history of one of the biggest supply chain disasters according to SC Digest....

June 2003: Wal-Mart’s then CIO Linda Dillman announces the start of the retailer’s EPC compliance program at a meeting of the VICS organization, saying Wal-Mart would ask its top 100 suppliers to begin tagging pallets and cases starting in January 2005.

August 2003: Wal-Mart says it will require all of its suppliers to put RFID tags carrying Electronic Product Codes on pallets and cases by the end of 2006… Continue

Technical Problems with RFID

Walmart RFID Requirement Taken from http://www.rfidjournal.com/article/view/642/1/1
The retailer plans to use a 96-bit EPC with a Global Trade Identification Number, an international standard. It is only interested in tags that operate in the UHF spectrum, which was defined as 868 MHz to 956 MHz. Class 1, Class 0 and Class 0 Plus (a read-write version of Class 0) tags are acceptable, but Dillman said Wal-Mart would like to see suppliers to move to Class 1 version 2 as soon as the specific… Continue

GTIN implementation in the Produce Industry

1. Traceability in Produce Industry using GTIN
The produce industry handles an estimated 6 billion cases of produce in the United States each year. Most produce can be tracked from company to company through the supply chain, provided companies comply with the one step forward and one step back requirements of the U.S. Bioterrorism Act of 2002. In addition, since 1930 U.S. produce companies have been required to retain records under the U.S. Perishable Agricultural Commodities Act to prov… Continue

Windows XP Embedded Advantages

We are using XP Embedded to drive ProPrint and Imager Pro applications. There are several advantages to this operating system:

1. Strips out all the unnecessary windows components leaving a smaller foot print for the operating system, around 500mb. This allows us to utilize the more industrial flash drives which provide better durability in industrial environments.

2. XP Embedded comes with write protect. On the main drive where the operating is stored, we write protect this drive. Any changes… Continue

Calibrate the Printer

For optimum print quality the printer software must know the actual
encoder-ticks-per inch and pen positions relative to the product
sensor. This document describes the procedure installation technicians
should follow to determine these settings and enter them into the
application software.

These settings not only affect "pen-crossing-alignment" but also actual
print quality (i.e. image and character edge sharpness). If they are not
set properly then optimum print quality will be never be achie… Continue
