配色来回打样七八次，交期全耽误。打样三次内算配合，流程顺才是真配合。
打样七八次，交期全耽误
TPE 配色定制是“配合活”：色卡、打样、交付。结论先给：色卡给得准，三次打样内定色才叫配合——配合，是定制的效率。
TPE配色定制最大的坑：色卡没给清来回打七八次，交期全被拖垮——配合，是定制的成本。
配色是效率关：流程顺，打样快。流程乱，来回拖——配色，是定制的效率题。
打样是时间成本，为什么限次数
打样费时：一次一周期。打样，是定制的时间账。
沟通成本：信息不清来回试。沟通，是定制的隐形账。
色差难控：色粉批次影响。色差，是定制的质量账。
色卡、打样、交付，流程怎么走
色卡：先给目标色卡。色卡，是头一站。
打样：三次内锁定。打样，是第二站。
交付：色差验收。交付，是第三站。
打样次数，一张表对照清楚
| 次数 | 含义 | 判断 |
|---|
| 1-3 | 配合好 | 达标 |
| 4-5 | 沟通差 | 改进 |
| 6+ | 有问题 | 复盘 |
| 色差 | 未锁 | 返工 |
表格读法：次数越少配合越好，首样就把光源和ΔE标上。
配合，是定制的效率。
三次内定色，流程核这四项
| 项目 | 要求 | 判断 |
|---|
| 色卡 | 明确 | 达标 |
| 打样 | ≤3次 | 达标 |
| 色差 | ΔE<1 | 达标 |
| 交付 | 准时 | 达标 |
表格读法：定制一项项核，效率看得见，ΔE控制在1.5以内再量产。
配合，是定制的成本。
色卡不给来回试，时间全耗光
坑一：色卡不给。拿一张照片就让配色，十次也对不准——色卡必给。
坑二：来回试。费时——流程必顺。
坑三：色差不锁。返工——色差必锁。
色卡、公差、次数——定制前讲清
三问：什么色卡、什么流程、什么色差。一验：打样实测——三问一验，供应商底细清楚。
配合验证要先行：先把色卡、观察光源、ΔE公差定死，再开始打样——配合，是定制的效率。
留样要成习惯：每批留样，物性按批次复测。批次换料先对比再放量——批次稳，客诉少。
反复打样、交期拖、色差：对照一张表
| 现象 | 原因 | 对策 |
|---|
| 来回拖 | 流程乱 | 走流程 |
| 色差大 | 没锁色 | 锁色差 |
| 交期废 | 次数多 | 控次数 |
| 返工 | 色卡缺 | 先给卡 |

配色来回拖，不是供应商笨，是流程没立起来。先给色卡、锁色差、定次数，三次内必出。
打样先要实物色卡或潘通色号。只发一张手机照片打样，十次也对不上。
ΔE≤1.5 算合格，超过 2.0 客户肉眼就能分。深色、荧光色打样次数多，先把预期谈拢。
打样七八次还偏色，光时间就耗掉半月。次数封顶写进合同，超了要么改配方要么加钱。
色库存档常用色，下次直接调样。同一批色号，第二次打样当天就能确认。

Color matching was proofed back and forth seven or eight times, delaying the delivery schedule. Providing three proofs or fewer counts as cooperation; smooth processes are real cooperation.
We went through seven or eight proofing rounds, and the delivery schedule was completely delayed.
TPE color customization is "cooperative work": color swatches, sample proofing, and delivery. Here's the conclusion first: giving accurate color swatches, and finalizing the color within three sample proofs is what real cooperation means—cooperation is the efficiency of customization.
The biggest trap in TPE color customization: the color swatches weren't provided clearly, requiring seven or eight back-and-forth rounds, and the delivery schedule was completely disrupted — cooperation is the cost of customization.
Color matching is about efficiency: when the process is smooth, proofing is fast. When the process is chaotic, it drags back and forth—color matching is a question of efficiency in customization.
Proofing is a time cost, why limit the number of times?
Proofing is time-consuming: one cycle at a time. Proofing is a time account for customization.
Communication cost: unclear information leads to repeated attempts. Communication is a customized invisible bill.
Color difference is hard to control: the batch of color powder has an impact. Color difference is the quality account of customization.
Color swatches, proofing, delivery—what is the process?
Color swatch: First provide the target color swatch. The color swatch is the first stop.
Proofing: Locked within three times. Proofing is the second stage.
Delivery: Color difference acceptance. Delivery is the third stop.
Number of proofs, one sheet for clear reference
| Number of times | Meaning | Judgment |
|---|
| 1-3 | Cooperate well | Meet the standard |
| 4-5 | Poor communication | Improve |
| Six | There is a problem | Review |
| Color difference | Unlocked | Return to work |
Table reading: The fewer times it is used, the better the coordination; for the first sample, mark the light source and ΔE.
Collaboration is the efficiency of customization.
Three times internal color setting, process verification of these four items
| Project | Requirement | Judgment |
|---|
| Color swatch | Clear | Meet the standard |
| Proofing | ≤3 times | Meet the standard |
| Color difference | ΔE<1 | Meet the standard |
| Delivery | On time | Meet the standard |
Table reading method: Customize and check each item, efficiency is visible, and mass production is carried out only when ΔE is controlled within 1.5.
Coordination is the cost of customization.
The color swatch won't allow back-and-forth testing, and all the time is wasted.
Pitfall 1: Not providing the color card. Using just a photo to match the color can be inaccurate even ten times—always provide the color card.
Pitfall 2: Trial and error back and forth. Time-consuming — the process must be followed correctly.
Pitfall three: Color difference not locked. Rework — color difference must be locked.
Color swatch, tolerance, number of times—clarify before customization
Three questions: what color card, what process, what color difference. One verification: actual measurement of the sample——three questions and one verification, the supplier's details are clear.
Coordination for verification should come first: first fix the color swatch, the observation light source, and the ΔE tolerance, then start proofing—coordination is the efficiency of customization.
Making sample retention a habit: retain samples for each batch, and re-test the physical properties by batch. Before switching materials between batches, compare them first before scaling up—the batch stability is maintained, and customer complaints are reduced.
Repeated proofreading, delayed delivery, color differences: compared in a table
| Phenomenon | Reason | Countermeasure |
|---|
| drag back and forth | The process is chaotic | Follow procedures |
| Large color difference | Unlocked color | Lock color difference |
| Delivery date canceled | frequent | Number of controls |
| Return to work | Missing color card | Give the card first |
| Customer Complaint | Poor cooperation | Set standards |
Going back and forth on color matching isn't because the supplier is incompetent, it's because the process hasn't been set up. First provide the color swatch, lock the color difference, set the number of attempts, it must be done within three tries.
Proofing requires a physical color swatch or Pantone color number first. Sending just a photo from a phone for proofing won't match even after ten attempts.
ΔE≤1.5 is considered acceptable; if it exceeds 2.0, the customer can see it with the naked eye. For dark or fluorescent colors, multiple proofs are needed, so align expectations first.
After seven or eight proofing attempts it still has color deviations, and just the time spent has already taken half a month. The maximum number of attempts is written into the contract; if it exceeds that, either the formula must be changed or extra money must be paid.
Common colors are kept in the color archive, so next time you can adjust samples directly. For the same batch number, the second sample can be confirmed on the same day.
The back-and-forth with color matching isn't because the supplier is incompetent, it's because the process hasn't been established.
. First, lock the color difference for the color card within three attempts guaranteed. For sample production, a physical color card or Pantone color number is required; sending only mobile phone photos for sampling cannot match the color even after ten tries.
ΔE ≤ 1.5 is considered acceptable; over 2.0 can be distinguished by the naked eye
For dark fluorescent colors, when there are many proofs, first align on expectations, cap the number of proofs in the contract, and if exceeded, either revise the formula or pay extra. For color inventory and commonly used colors, the second proof should be confirmed on the same day.
After seven or eight proofing attempts with color deviations, half a month was already spent just on the timing.
If the maximum number of times is written into the contract and exceeded, either adjust the formula or pay extra. For color inventory files, commonly used colors can be sampled directly next time. The second sampling of the same batch color number can be confirmed on the same day.
Common colors in the color inventory can be adjusted directly for sampling next time
. For the same batch of color codes, the confirmation can be made on the day of the second sample run. A ΔE≤1.5 is considered acceptable, while exceeding 2.0 can be distinguished by the naked eye. For dark and fluorescent colors that require multiple sample runs, first settle the expectations and write the maximum number of runs into the contract.
The back-and-forth with color matching isn't because the supplier is incompetent, it's because the process hasn't been established.
First, the color chart should have the color difference locked, and it must appear within three attempts. For proofing, you need a physical color card or a Pantone color number; sending just one mobile photo will not match even after ten proofing attempts.
The back-and-forth with color matching isn't because the supplier is incompetent, it's because the process hasn't been established.
First, set the color card color difference lock to a limited number of attempts, with a proof output guaranteed within three tries. A physical color card or Pantone color code is required. ΔE ≤ 1.5 is considered qualified; if it exceeds 2.0, it can be seen with the naked eye. The number of attempts is capped and should be written into the contract.
Cologne Customer Case: Hardness drift and inconsistent touch, small batch trial production experienced low-temperature bending issues
A modified material application factory in Hefei has TPE colored parts with hardness batch drift, feeling alternately soft and hard. Cologne will cooperate with small batch trial production verification before scaling up, with stable hardness, passing the -40°C low-temperature bending test in one go. In small batch trial production, lock the batch before scaling up—regarding the drift issue, first look at the system stability.
Summary
The process of TPE color customization starts with providing the color swatches, then controlling through sample production. Only if the color can be finalized within three attempts can it be called true cooperation; cooperation is efficiency.
