　　FTP sites are currently being considered as a future requirement. FTP暂为将来必备项

　　5. In-House Testing Equipment必备测试设备

　　Spectrophotometer: X-Rite 528, 530, 939,or SpectroEye (former Gretag Macbeth model)分光密度仪：X-Rite 528, 530, 939, 或SpectroEye(原Gretag Macbeth的型号)

　　IMPORTANT NOTE: Lowe’s stores utilize a F2 light source. Therefore all color, readings must utilize the F2/10° (illuminant/viewing angle) settings on spectrodensitometers. This is important to know as most spectrodensitometers are defaulted to D50 or D65 illuminants. It is also important to know that spectrodensitometers need to be set to “Status T” for brightness and whiteness readings. 郑重提示：Lowe’s商店里使用F2光源。因此，使用分光密度仪读取颜色时，请将光源/角度设置为F2/10°。因多数分光密度仪的光源默认设置为D50或D65，这点极为重要。另外，务必请将分光密度仪的亮度和白度设置为”Status T”。

　　Status T: Wide band color reflection densitometer response, which is the accepted standard in the United States for color reflection densitometers.Status T：设置为Status T时，密度仪读取的颜色反射区域宽，符合美国对颜色反射密度检测的标准要求。

　　Bursting Strength Tester耐破测试仪

　　Production is required to Burst test final product to confirm production has not degraded structural integrity of paper.生产过程中，必须对最终产品进行耐破测试，以确保纸张间完全粘合、瓦楞板强度达标。

　　IMPORTANT NOTE: Lowe’s mandates corrugated packaging to pass burst performance requirements defined by brand/category. If an ECT board is specified by a design, the board must pass both the ECT test and also pass the “equivalent” burst standard.Lowe’s强制要求瓦楞包装必须达到其品牌或所属产品类别所要求的破断力，并能够通过测试。如设计要求规定了ECT(边压)，则该瓦楞板必须在通过规定值的边压测试外，还必须同时通过相应的耐破测试。

　　Sutherland Rub Tester摩擦测试仪

　　Barcode verifier with Grading带分级的条码检测仪

　　6. Press side Lighting Conditions (for SPOT Color) 印刷机边的光源环境(针对专色)

　　F2 lighting is required press side ONLY IF the printer wishes to visually confirm color in addition to the required method of measuring and monitoring color with a Spectrophotometer. Otherwise, D50 and D65 are acceptable a general review of print.一般情况下，在D50或D65光源下检查印刷品的颜色即可。如果印刷厂想在分光密度仪检测的基础上，再目视检查确认颜色的情况下，才需要F2光源。

　　*(F2 is cool white fluorescence with a color temperature of 4200K)(F2是一种色温为4200K的白色荧光冷光灯)

　　7. In-House Conditional Requirements可选测试设备

　　Edge Crush Test Machine (OPTIONAL if company runs ECT grades of board)

　　边压测试仪(对需进行边压测试的公司可选)

　　Production is required to Burst test final product to confirm production has not degraded structural integrity of paper.最终产品必须做耐破检测，以确保产品所用瓦楞板结构性强度不低于要求。

　　8. Minimum Printing Press Requirements对印刷车的最低要求

　　a. Size: 1500mm x 2200mm (59” x 86”) 尺寸：1500mm x 2200mm (59”x 86”)

　　b. Colors: 2 颜色：2色

　　c. Ability to print a minimum line screen of 35 lines per inch (lpi).印刷精度不低于35线/英寸

　　d. Ability to produce any item with a blank size of 2159mm x 1473mm (85” x 58”) or less as 1 piece. 必须能够不拼接生产任何展开尺寸小于等于2159mm x 1473mm (85”x 58”)的产品。

　　IMPORTANT NOTE: 郑重提示：

　　All printed items with a blank size of 2159mm x 1473mm (85” x 58”) or less must be manufactured as 1 continuous piece. This means that an item cannot be created by assembling 2 or more pieces.任何产品,只要展开尺寸不大于2159mm x 1473mm (85”x 58”)，都必须是一片生产，不得用2片或2片以上拼接而成。

　　9.Coating / Varnishing Capability 能做表面涂层或上光

　　In-house 工厂内部

　　10. Corrugator size and Flute Profiles 瓦楞生产线的幅宽和瓦楞板的波形要求

　　The printer must have a Minimum Corrugator width of 1400mm (55”) with A, B, C, E, and BC capabilities supplying their facility with paper.瓦楞板生产线，可产幅宽不低于1400mm (55”)，波形为A浪、B浪、C浪、E浪和BC浪的瓦楞板。

　　11. Die Cutting Capability 模切设备

　　In-house 工厂内部

　　12. Spot Color Matching 专色跟准

　　Printer is expected to match all color standards within a DEcmc of 2.0 with L2:c1:cf2.0 settings.在分光密度仪设置为L2:C1:Cf2.0的情况下，要求印刷厂跟准标准色，并将色差控制在Decmc值2.0以内。

　　Production Note for Manufacturer’s Joints产品的连接

　　Lowe’s discourages the use of staples and excessive taping whenever possible. Lowe’s prefers that packaging be supplied with a good glue adhesive and glue bond in the glue joints to these other methods of bonding a manufacturer’s joint. 只要可能，尽量不使用骑马钉和过多使用胶带。对于产品的接缝，Lowe’s更倾向于使用高品质的胶水粘合。

　　**Burst Strength/ ECT耐破/边压测试

　　Lowe’s mandates Burst Strength Requirements. ECT board can be used if a vendor chooses. In these situations, the board must pass both the ECT test and the “equivalent” Mullen test. The pass/ fail criteria are that the results of the test meet the specified board utilizing the testing methods stated below.耐破测试是Lowe’s要求的必测项目。供应商可以选择边压测试，但在此情况下，测试样板必须同时通过边压测试和对应的Mullen测试(纸板耐破度测试)。是否通过测试的判断标准为：按下文所列的方法进行测试，所得结果达到该规格纸板所要求的额定值。

　　Burst Strength test耐破测试

　　A minimum of six bursts must be made, three from each side of the board, and only one burst test will be permitted to fall below the specified minimum value. Board failing to pass the foregoing test will be accepted if in a retest consisting of 24 bursts, twelve from each side of the board, not more than four burst tests fall below the specified minimum value. Disregard non-simultaneous bursts.最少要测6次，纸板样两边各测3次，其中只允许有一次的结果低于规定的最低额定破断力。未通过测试的纸板允许重测，但重测时要做24次耐破测试，纸板两边每边各测12次。24次中，未达额定最低破断力的次数小于等于4次的情况下，视为通过测试。

　　Edge Crush test边压测试

　　A minimum of six tests must be made and only one test is permitted to fall below the specified minimum value, and that one test cannot fall below the specified minimum value by more than 10%. Board failing to pass the foregoing will be accepted if in a retest consisting of 24 tests, not more than four tests fall below the specified minimum value and none of those tests fall below the specified minimum value by more than 10%.最少要做6次，当未达标次数小于等于一，且与标准值的差距在10%以内时，为通过。未过测试的纸板可以重测，但重测时要求测24次，且未达标次数小于等于四，低于标准值不超过10%时，可视为通过测试。

　　*** cmc is a tolerencing method that is defined by 3 parameters: L= light value, c = chroma, cf = commercial factor

　　cmc是以以下三个参数确定颜色公差的方法：L = 辉度，c = 色度，cf = 商业因素

　　**** Although the color to color maximum variation is defined, different designs may require tighter registration to be visually pleasing and it is the printer’s obligation to supply the best quality product as required by the graphics.尽管我们已对颜色与颜色的偏差值做了规定，但是，鉴于不同的设计可能会对套色的要求会有不同，某些设计可能会对套色有更高的要求，印刷厂商有义务且必须按照设计稿的要求制作生产产品，并确保有良好的视觉效果。

　　***** Board Lamination - fold front & back along the flute direction & perpendicular to the flute direction to determine the lamination of corrugated board瓦楞板纸张间的粘合 - 沿瓦楞方向和垂直与瓦楞方向前、后折瓦楞板数次，以确定瓦楞板各层纸张间粘合良好，无分层。

　　Guidelines under Consideration for Possible Future Requirements

　　Direct print Flexography on Corrugated

　　Manufacturer's Joint接缝

　　No Staples - glue bond only不得使用骑马钉 - 只能用胶粘

　　* Absolute Density takes the substrate into consideration绝对密度已将面纸考虑在内

　　** Although .03D is maximum difference between the densities of reflected light for RGB, it is only a guideline. The printer must recognize that different combinations of RGB reflectance can visually shift the hue of gray. It is also very IMPORTANT to note that the required balance between C, M, and Y to achieve a balanced gray resulting in equal balance of the densities for R, G, and B can ONLY be achieved using the correct press profile for the ink, press, substrate and line screen combination being used to reproduce the print.

　　0.03D虽然是可接受的最大RGB光反射密度值，但仅作参照标准。印刷商必须认识到RGB三通道间随灰平衡组合变化将影响灰色的视觉色调。非常重要的是，不同模式下，要使C、M、Y间达到与R、G、B时同样密度的灰平衡，印刷厂必须根据需要调整印刷时使用合适的油墨、压力、面纸及印刷精度(线/英寸)等，以期达到设计要求。
