Problems……………… Checks is that the repeating size is not constant but variable. If the repeat is not constant, we cannot plan a marker exactly on a repeat. Checks is that the repeating size is not constant but variable. If the repeat is not constant, we cannot plan a marker exactly on a repeat. Fabric produced on industrial looms and finished using the correct method is normally of such good quality that we are able to plan markers exactly on the repeat, spread the fabric according to the repeat and cut the lay package later obviating block cutting and relaying the pieces later for single piece matching.

Basic Level of Technology The basic level of technology is creating markers on a computerized marker generation system with matching points for plaid/checks and a provision for block cutting. The basic level of technology is creating markers on a computerized marker generation system with matching points for plaid/checks and a provision for block cutting. The real size marker layout will be taken out from the plotter. During spreading of fabrics using a spreader or manually, the fabric is laid with one side of the selvedge aligned. The real size marker layout will be taken out from the plotter. During spreading of fabrics using a spreader or manually, the fabric is laid with one side of the selvedge aligned. This way, the best possible lengthwise stripe match is realized. The paper marker is kept on the lay and a straight knife used. During cutting, single or dual pattern blocks are cut using a straight knife. This way, the best possible lengthwise stripe match is realized. The paper marker is kept on the lay and a straight knife used. During cutting, single or dual pattern blocks are cut using a straight knife. Then the stack component is re-laid on a pintable, manually matching stripes, either length or widthwise, layer by layer. Then the stack component is re-laid on a pintable, manually matching stripes, either length or widthwise, layer by layer. If a pintable is not used, then during re-laying, pins are often used from the top of the stack to avoid interplay slippage in the stack. Then precision cutting is done using a band knife.

Intermediate Level of Technology The intermediate level of technology is creating markers on a computerized marker generation system with matching points for plaid/checks. The intermediate level of technology is creating markers on a computerized marker generation system with matching points for plaid/checks. A full size marker plot is taken on a paper and the fabric is manually spread (no spreader is used) using continuous pin tables for perfect alignment of the plaids during spreading.

Highest level of technology The highest level of technology is by creating markers on a computerized marker generation system with matching points for plaid/checks and spreading the fabric using a continuous pintable to prepare lay packages similar to the intermediate level. The highest level of technology is by creating markers on a computerized marker generation system with matching points for plaid/checks and spreading the fabric using a continuous pintable to prepare lay packages similar to the intermediate level. Here the lay will be cut using CNC-Cutter (CAM) which is equipped with a camera system in order to do the final adjustment (2-3 mm) in the position of the patterns related to the lay package. Here the lay will be cut using CNC-Cutter (CAM) which is equipped with a camera system in order to do the final adjustment (2-3 mm) in the position of the patterns related to the lay package. This step needs the operator and can be understood to be semi- automatic. The digital camera and associated light box analyze the exact position of motifs on the cutting surface. This step needs the operator and can be understood to be semi- automatic. The digital camera and associated light box analyze the exact position of motifs on the cutting surface. The on-cutter scanner detects the fabric’s actual motif, analyses distortion, modifies markers and geometry of pieces in real time based on the fabric’s physical characteristics and automatically launches the calculation and cutting process. The on-cutter scanner detects the fabric’s actual motif, analyses distortion, modifies markers and geometry of pieces in real time based on the fabric’s physical characteristics and automatically launches the calculation and cutting process. This eliminates need for material to be ‘block’ cut and the result is absolutely astonishing regarding accuracy. It reduces labor and material costs because there is no need for skilled operators to manually match fabrics.

It may be noted that different levels of technology do not result in different levels of quality; rather it is time and manpower that is saved while using the higher levels of technology. In case of striped knitwear, however, a continuous pintable is preferred over a block pin table as the stripes in circular knit fabric are always at an angle and only a continuous pintable offers angular alignment of pins.

Value for Money The higher the technology level, the better the benefit in terms of productivity realized. The Return on Investment for different equipment differs, based on scale of operation and types of merchandise produced, etc. Here I will give examples of two generic pieces of equipment The higher the technology level, the better the benefit in terms of productivity realized. The Return on Investment for different equipment differs, based on scale of operation and types of merchandise produced, etc. Here I will give examples of two generic pieces of equipment (AUTOMATIC SPREADER) (PIN TABLE)

Example ROI for Automatic Spreader: Fabric Saving: Fabric Saving: We can save fabric on the spreading machine by making longer layers. We can save fabric on the spreading machine by making longer layers. Make 3 m long marker with 200 plies. Make 3 m long marker with 200 plies. 2 cm end loss on each side is 800 cm in total. 2 cm end loss on each side is 800 cm in total. 12 m and reduce the plies by m and reduce the plies by 150. Now the end losses will be 50x4 = 200cm. Now the end losses will be 50x4 = 200cm. Thus saving 600cm fabric or 1.0% of fabric. Thus saving 600cm fabric or 1.0% of fabric. Splicing also generates around 0.75% of savings. Splicing also generates around 0.75% of savings. Total savings by using the spreader is 1.75%. Total savings by using the spreader is 1.75%. Fabric price is Rs 50/meter Fabric price is Rs 50/meter Spreading 5,000 m / day. Spreading 5,000 m / day. Saving of (1.75% x 50 x5000) = Rs 4,375 per day = Rs 13, 12,500 per year (300 days/year).

ROI for continuous Pin Table: we can avoid most blocking tolerances, we work with smaller patterns, i.e., fabric consumption is reduced. This depends on the size of the repeat-according to our experience, 3% saving is an average figure. But we argue Normally with just 2%when talking to Customers in order to be on the we can avoid most blocking tolerances, we work with smaller patterns, i.e., fabric consumption is reduced. This depends on the size of the repeat-according to our experience, 3% saving is an average figure. But we argue Normally with just 2%when talking to Customers in order to be on the Conservatives idea and still get a good ROI 2% (saving) x 1.8 m (consumption) x 550 (shirts/day/8h- shift)xUS$3.5 (price of fabric/m)=US$6,930 saving per day; 2% (saving) x 1.8 m (consumption) x 550 (shirts/day/8h- shift)xUS$3.5 (price of fabric/m)=US$6,930 saving per day; investment of US$20,000, investment of US$20,000, Get ROI of 288 days, which is less than 9 months.
