是一個馬達驅動的機器移動打印標本通過一個弧形的加權試紙。The Sutherland Rub Tester has been redesigned to improve its operation.薩瑟蘭擦測試機已被重新設計，以改善其運作。James River's corporate research and development laboratories did extensive testing of the Sutherland Rub Tester.詹姆斯河的企業研究和開發實驗室薩瑟蘭擦試驗機廣泛的測試。The result of this work is an affordable abrasion testing instrument that retains all the features that made it an industry standard plus improvements that ensure it will remain the industry standard.這項工作的結果，是一種經濟實惠的耐磨測試機，保留所有的功能，使得它的行業標準，加上改進，以確保它仍將是行業標準。

The stroke of the tester has been shortened which increases the precision and more closely simulates abrasion damage found in the field.測試機的行程已縮短，從而提高精度和更加緊密地模擬在現場發現的磨損損壞。James River research and other published work in the print abrasion testing arena have shown that quick strokes simulate some types of rub damage (most notably shipping damage).詹姆斯河的研究，並發表在其他打印磨損測試領域的工作已經表明，快速的筆觸模擬擦某些類型的損害（最顯著的運輸損壞）。

A single mounting pad for the test strip is now cut to fit the weight.現在安裝一個單一的試紙條的墊以適合的重量。It was found that precision of the test is increased by using a 2 inch (5 cm) by 4 inch (10 cm) pad on the bottom of the weight .結果發現，測試精度是通過使用2英寸（5厘米），4英寸（10厘米），重量底部墊增加。Two pound and four pound weights and scoring fixture are included.包括兩磅和4磅重的重量和得分夾具。

A supply of 80 x 80 count bleached muslin cloth (cloth not included) has been found useful in testing wet smear, wet rub, and wet bleed.80 × 80的計數漂白的薄紗佈（不包括佈）的供應，已發現有用的測試濕塗片，濕擦，濕出血。The Sutherland Rub Tester is designed to evaluate the scuffing or rubbing resistance of the printed or coated surface of paper, paperboard, film, etc. The test results are reproducible.薩瑟蘭擦試驗機的目的是評估印刷的紙張或塗層表麵耐劃傷或摩擦，紙板，薄膜等的測試結果重復性。

The following tests may be made with the instrument:下麵的測試，可能與機器：

• Dry Rub乾擦
• Wet Rub濕擦
• Wet Bleed or Transfer濕出血或接送

• Wet Smear濕塗片
• Functional Rub功能擦

The test requires two pieces of stock, the printed test specimen and a test receptor, which is usually unprinted.測試需要兩件貨，打印的測試樣品和測試受體，它通常是未打印。Cut a test specimen, approximately six by three inches, representing average ink lay and coverage.剪切試樣，約六三英寸，相當於平均油墨裁員和覆蓋麵。When the printed area permits, the six inch direction should be cut across the grain of the sheet, but must not cross pressed or cut scores.6英寸方向的印刷麵積允許時，應切斷整個表的糧食，但不得跨按下或削減的分數。

Prepare test strips of unprinted material from the same shipment of stock used in printing the test samples.準備從相同的股票在打印測試樣本用於裝運未打印材料的試紙。Cleanly cut 2 x 7 inch strips for the four-pound weight are prepared by placing a strip face down against the end pin of the scoring device and scoring the strip at the white dot positions to facilitate bending the strip to conform to the test block.乾凈切為四磅重的2 × 7英寸帶準備放置一個帶麵，對計分設備結束針得分地帶白點的位置，以方便彎曲的地帶，以符合試塊。

To prepare samples for the two-pound weight, 2 x 5-1/4 inch strips are placed face down against the end pin of the scoring device and score at the red dot position to facilitate bending the strip to conform to the test weight.要準備兩磅重的樣品，放置2 × 5-1/4英寸帶麵朝下對計分設備的結束針，在紅點的位置，以方便彎曲的地帶，以符合重量測試的得分。
